编写窗体应用程序，安排一个文本框、一个按钮和一个标签，从文本框录入一个数字（0～9），点击按钮将其对应的英文单词(如：zero，one等)显示在标签中。

这是一个编程问题，可以使用 C#、Java、Python等编程语言实现。以下是使用 C#实现的代码示例：

private void button1_Click(object sender, EventArgs e)
{
    string[] words = { "zero", "one", "two", "three", "four", 
                      "five", "six", "seven", "eight", "nine" };
    int num = Int32.Parse(textBox1.Text);
    label1.Text = words[num];
}

在该代码中，首先定义了一个字符串数组，保存数字 0～9 对应的英文单词。当用户点击按钮时，从文本框中获取数字，使用 Int32.Parse()方法将其转换为整数类型。然后，根据该数字在数组中寻找对应的英文单词，并将其显示在标签中。

java编写窗体应用程序，安排一个文本框、一个按钮和一个标签，从文本框录入一个数字（0～9），点击按钮将其对应的英文单词(如：zero，one等)显示在标签中。

好的，这是一个非常基础的GUI编程问题，以下是java实现的一种方式：

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class NumberToWordConverter extends JFrame implements ActionListener {

    private JLabel label;
    private JTextField textField;
    private JButton button;

    public NumberToWordConverter() {
        setTitle("数字转英文单词");
        setLayout(new FlowLayout());

        label = new JLabel("输入数字：");
        add(label);

        textField = new JTextField(5);
        add(textField);

        button = new JButton("转换");
        button.addActionListener(this);
        add(button);

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        pack();
        setVisible(true);
    }

    public void actionPerformed(ActionEvent e) {
        String input = textField.getText();
        int num = Integer.parseInt(input);

        String[] words = {"zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine"};

        if (num >= 0 && num <= 9) {
            label.setText(words[num]);
        } else {
            label.setText("输入有误！");
        }
    }

    public static void main(String[] args) {
        new NumberToWordConverter();
    }
}

上述代码创建了一个NumberToWordConverter类，继承了JFrame类，并实现了ActionListener接口。其中，包括一个标签、一个文本框和一个按钮，并在按钮被点击时触发actionPerformed方法进行事件处理。在方法中，根据输入的数字选择对应英文单词，并在标签中显示结果。此外，还增加了输入检查，如果输入不在0~9范围内，标签会显示“输入有误！”提示信息。

用java编写窗体应用程序，安排一个文本框、一个按钮和一个标签，从文本框录入一个数字（0～9），点击按钮将其对应的英文单词(如：zero，one等)显示在标签中 。进一步，扩展数据的范围（如：0～100），如何修改程序实现翻译。

以下是Java代码实现：

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class NumberToWordConverter extends JFrame implements ActionListener {
    private JTextField textField;
    private JLabel resultLabel;

    private String[] wordArray = {"zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine"};

    public NumberToWordConverter() {
        super("Number to Word Converter");

        // 设置窗体布局
        setLayout(new FlowLayout());

        // 创建文本框和标签
        textField = new JTextField(10);
        add(textField);

        JButton button = new JButton("Convert");
        add(button);

        resultLabel = new JLabel("");
        add(resultLabel);

        // 为按钮添加动作监听器
        button.addActionListener(this);

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(250, 100);
        setVisible(true);
    }

    public void actionPerformed(ActionEvent e) {
        String inputText = textField.getText();
        try {
            int number = Integer.parseInt(inputText);
            if (number >= 0 && number <= 9) {
                resultLabel.setText(wordArray[number]);
            } else {
                resultLabel.setText("Number out of range!");
            }
        } catch (NumberFormatException ex) {
            resultLabel.setText("Invalid input!");
        }
    }

    public static void main(String[] args) {
        new NumberToWordConverter();
    }
}

如果要扩展数据的范围到 0~100，可以修改 `wordArray` 数组为包含 101 个元素的字符串数组，其中前 10 个元素为 0~9 对应的英文单词，后面的元素为 10~100 对应的英文单词，可以通过一个 switch 语句实现转换。修改后的代码如下：

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class NumberToWordConverter extends JFrame implements ActionListener {
    private JTextField textField;
    private JLabel resultLabel;

    private String[] wordArray = {"zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine",
                                  "ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen",
                                  "seventeen", "eighteen", "nineteen", "twenty", "twenty-one", "twenty-two",
                                  "twenty-three", "twenty-four", "twenty-five", "twenty-six", "twenty-seven",
                                  "twenty-eight", "twenty-nine", "thirty", "thirty-one", "thirty-two",
                                  "thirty-three", "thirty-four", "thirty-five", "thirty-six", "thirty-seven",
                                  "thirty-eight", "thirty-nine", "forty", "forty-one", "forty-two", "forty-three",
                                  "forty-four", "forty-five", "forty-six", "forty-seven", "forty-eight",
                                  "forty-nine", "fifty", "fifty-one", "fifty-two", "fifty-three", "fifty-four",
                                  "fifty-five", "fifty-six", "fifty-seven", "fifty-eight", "fifty-nine", "sixty",
                                  "sixty-one", "sixty-two", "sixty-three", "sixty-four", "sixty-five", "sixty-six",

                                  "seventy-seven", "seventy-eight", "seventy-nine", "eighty", "eighty-one",
                                  "eighty-two", "eighty-three", "eighty-four", "eighty-five", "eighty-six",
                                  "eighty-seven", "eighty-eight", "eighty-nine", "ninety", "ninety-one",

                                  "ninety-seven", "ninety-eight", "ninety-nine", "one hundred"};

    public NumberToWordConverter() {
        super("Number to Word Converter");

        // 设置窗体布局
        setLayout(new FlowLayout());

        // 创建文本框和标签
        textField = new JTextField(10);
        add(textField);

        JButton button = new JButton("Convert");
        add(button);

        resultLabel = new JLabel("");
        add(resultLabel);

        // 为按钮添加动作监听器
        button.addActionListener(this);

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
