可以尝试使用QSS（Qt Style Sheets）来美化界面。例如，可以在窗口初始化的时候添加以下代码：

self.setStyleSheet(
    """
    QPushButton {
        background-color: #A3C1DA;
        color: black;
        font-weight: bold;
        border-radius: 5px;
        border: 2px solid #555555;
        padding: 5px;
    }
    QPushButton:hover {
        background-color: #C9E2F3;
        color: #555555;
    }
    """
)

这段代码会将所有QPushButton的背景颜色改为浅蓝色，字体颜色改为黑色，字体加粗，圆角半径设置为5px，边框宽度为2px，边框颜色为深灰色，内边距为5px。当鼠标悬停在按钮上时，背景颜色改为淡蓝色，字体颜色改为深灰色。

你也可以根据自己的需要调整样式。

你可以将上述代码中的布局添加到一个 QVBoxLayout 中，然后将 QVBoxLayout 设置为 QWidget 的布局，再将 QWidget 作为 QMainWindow 的 central widget，即可实现居中排列。示例代码如下：

button_layout = QGridLayout() 
button1 = QPushButton('当日员工工资') 
button1.setFixedSize(200, 50) 
button1.setStyleSheet('QPushButton {background-color: #A3C1DA; color: black; font-weight: bold;}') 
button1.clicked.connect(self.show_query1_result) 
button_layout.addWidget(button1, 0, 0)  

button2 = QPushButton('当日鸡爪领取记录') 
button2.setFixedSize(200, 50) 
button2.setStyleSheet('QPushButton {background-color: #A3C1DA; color: black; font-weight: bold;}') 
button2.clicked.connect(self.show_query2_result) 
button_layout.addWidget(button2, 0, 1)  

button3 = QPushButton('查询历史员工工资') 
button3.setFixedSize(200, 50) 
button3.setStyleSheet('QPushButton {background-color: #A3C1DA; color: black; font-weight: bold;}') 
button3.clicked.connect(self.show_query3_result) 
button_layout.addWidget(button3, 1, 0)  

button4 = QPushButton('查询历史鸡爪领取记录') 
button4.setFixedSize(200, 50) 
button4.setStyleSheet('QPushButton {background-color: #A3C1DA; color: black; font-weight: bold;}') 
button4.clicked.connect(self.show_query4_result) 
button_layout.addWidget(button4, 1, 1)  

button5 = QPushButton('按员工ID查询员工工资') 
button5.setFixedSize(200, 50) 
button5.setStyleSheet('QPushButton {background-color: #A3C1DA; color: black; font-weight: bold;}') 
button5.clicked.connect(self.show_query5_result) 
button_layout.addWidget(button5, 2, 0)  

button6 = QPushButton('按员工ID查询鸡爪领取记录') 
button6.setFixedSize(200, 50) 
button6.setStyleSheet('QPushButton {background-color: #A3C1DA; color: black; font-weight: bold;}') 
button6.clicked.connect(self.show_query6_result) 
button_layout.addWidget(button6, 2, 1)  

button_layout.setColumnStretch(2, 1) # 添加空白列来填充布局  

v_layout = QVBoxLayout() 
v_layout.addStretch() # 添加弹性空间，使按钮布局垂直居中
v_layout.addLayout(button_layout) 
v_layout.addStretch() # 再添加一次弹性空间

要将按钮布局设置为两列，可以使用QGridLayout而不是QVBoxLayout。可以使用addWidget()方法将按钮添加到布局中，并指定它们的位置。以下是示例代码：

button_layout = QGridLayout()
button1 = QPushButton('当日员工工资')
button1.setFixedSize(200, 50)
button1.setStyleSheet('QPushButton {background-color: #A3C1DA; color: black; font-weight: bold;}')
button1.clicked.connect(self.show_query1_result)
button_layout.addWidget(button1, 0, 0)

button2 = QPushButton('当日鸡爪领取记录')
button2.setFixedSize(200, 50)
button2.setStyleSheet('QPushButton {background-color: #A3C1DA; color: black; font-weight: bold;}')
button2.clicked.connect(self.show_query2_result)
button_layout.addWidget(button2, 0, 1)

button3 = QPushButton('查询历史员工工资')
button3.setFixedSize(200, 50)
button3.setStyleSheet('QPushButton {background-color: #A3C1DA; color: black; font-weight: bold;}')
button3.clicked.connect(self.show_query3_result)
button_layout.addWidget(button3, 1, 0)

button4 = QPushButton('查询历史鸡爪领取记录')
button4.setFixedSize(200, 50)
button4.setStyleSheet('QPushButton {background-color: #A3C1DA; color: black; font-weight: bold;}')
button4.clicked.connect(self.show_query4_result)
button_layout.addWidget(button4, 1, 1)

button5 = QPushButton('按员工ID查询员工工资')
button5.setFixedSize(200, 50)
button5.setStyleSheet('QPushButton {background-color: #A3C1DA; color: black; font-weight: bold;}')
button5.clicked.connect(self.show_query5_result)
button_layout.addWidget(button5, 2, 0)

button6 = QPushButton('按员工ID查询鸡爪领取记录')
button6.setFixedSize(200, 50)
button6.setStyleSheet('QPushButton {background-color: #A3C1DA; color: black; font-weight: bold;}')
button6.clicked.connect(self.show_query6_result)
button_layout.addWidget(button6, 2, 1)

button_layout.setColumnStretch(2, 1) # 添加空白列来填充布局

layout = QHBoxLayout()
layout.addLayout(button_layout)
widget = QWidget()
widget.setLayout(layout)
self.setCentralWidget(widget)

在上面的代码中，`button_layout`是一个QGridLayout，使用addWidget()方法来添加按钮到布局中，并指定它们的行和列。`setColumnStretch()`方法用于添加一个空白列来填充布局，使其呈现为两列。
