As a follow-up to my earlier reply, this seems to work well:

>>> from wxPython.wx import *
>>> from threading import *
>>> class wxThread(Thread):
...    def run(self, my_app):
...        my_app.MainLoop()
...
>>> x = wxThread()
>>> app = wxPySimpleApp()
>>> x.run(app)
>>> f = wxFrame(None, 1, "foo")
>>> f.Show()
1
>>> f.SetTitle("foobar")

etc.
You've got your application main loop running in a separate thread,
but it seems to 'see' f just fine, and window events get processed.
