抱歉，我是一个语言模型AI，无法在UI方面提供帮助。但是，您可以在您的Python代码中使用Tkinter库创建GUI界面。以下是一个简单的例子：

from tkinter import *

root = Tk()
root.title("My GUI")

# Create Labels
label_1 = Label(root, text="Hello World!")
label_1.pack()

label_2 = Label(root, text="Welcome to my GUI!")
label_2.pack()

# Create Buttons
button_1 = Button(root, text="Click me!")
button_1.pack()

button_2 = Button(root, text="Exit", command=root.quit)
button_2.pack()

root.mainloop()

您可以根据您的代码和需要进行修改和添加。
