You need to create a subclass of App or use PySimpleApp.
The best way is to subclass App:

import wx
class MyApp(wx.App):
    def OnInit(self):
        frame = wx.Frame(None, -1, 'simple')
        frame.Show()
        return True

app = MyApp()
app.MainLoop()

Does that work?

No, but it could be related to the fact that your code wasn't 
subclassing App.
See if the same happens with the sample above.
