In wxPython, the main GUI window is called a Frame.

import wx BACKGROUNDCOLOR = (240, 240, 240, 255) class MainFrame(wx.Frame):     def __init__(self, *args, **kwargs):         wx.Frame.__init__(self, *args, **kwargs)         self.createWidgets()         self.Show()     def exitGUI(self, event):       # callback         self.Destroy()     def createWidgets(self):     self.CreateStatusBar() # wxPython ...
