Create a class that has a write(self, string) method, create an instance of
it and assign it to sys.stderr. Now anyhtin written to that output stream
(including exception messages) will actiually be written to your object. You
can do whatever you want with it, display in a window, write to a file, send
it in an email to yourself...
Take a look near the end of wx.py for an example, wxPyOnDemandOutputWindow.
One of these is created if you construct your wxApp object without the zero,
IOW, "app = MyApp(1)"
The one problem with redirecting sys.stdout and sys.stderr is that it tends
to make debugging with pdb very difficult, so you'll want to make it
something that is optional or easily disabled forwhen you want to debug.
