Okay, I used your recipe and got it to work.  Thanks!

I did have a problem with it.  wxApp under MS Windows starts a new 
window
to show stdout and stderr.  That window wasn't closed when the app 
finished,
which caused the error

  Debug: e:\projects\wx\src\msw\app.cpp(466): 'UnregisterClass(no redraw 
canvas)'
  failed with error 0x00000584 (class still has open windows.).

Deriving from wxPythonSimpleApp fixed it, and it turns out the real fix
is to set "redirect" to 0 in the wxApp constructor.  This prevents the
output window from opening.

I added this comment to the recipe as well.
