嗯，错误信息仍在继续：

...
QMessageBox.question(QWidget, QString, QString, QMessageBox.StandardButtons 
buttons=QMessageBox.Ok, QMessageBox.StandardButton defaultButton=QMessageBox.NoButton):
argument 1 has unexpected type 'Ui_MainWindow'
...

您的self不是QWidget，而是Ui_MainWindow。将self更改为self.centralwidget，它应该有效。

def programExit(self):
    quit_msg = "Are you sure you want to exit the program?"
    reply = QtGui.QMessageBox.question(self.centralwidget, 'Message', quit_msg, QtGui.QMessageBox.Yes, QtGui.QMessageBox.No)
    if reply == QtGui.QMessageBox.Yes:
        sys.exit()
    else:
        pass
