For pywrap to work you need to not automatically create the app and run 
the MainLoop when the module is imported.  Try it like this:


import wx

class MyFrame(wx.Frame):
     pass

class MyApp(wx.App):
     def OnInit(self):
         self.frame = MyFrame(None, -1, "Test")
         self.frame.Show()
         self.SetTopWindow(self.frame)
         return True

if __name__ == '__main__':
     app = MyApp()
     app.MainLoop()


This way pywrap can import the module and then create the instance of 
the application object itself.  It also calls MainLoop.
