Most of the wxPython toolkit is accessed through the wx package which you
access using the import wx statement. Every wxPython program must have
an application object—an instance of  a wx.App subclass that defines an
OnInit() method. Most wxPython programs will have one or more
frames—instances of subclasses of wx.Frame. A frame is the large, movable,
resizeable window-like container that appears on screen, often with a menu,
status bar, tool bars, and other widgets. Control of your program passes to
wxPython when you call your application’s MainLoop() method.
