Basically, I don't think this is possible. wxWindows and Excel (written in
MFC) application use different message handling loop instances and it's not
possible (for sure without access to source code) to integrate them.

It's possible to build MFC based applications in Python using Mark Hammond's
PythonWin. An excellent example of that is the PythonWin IDE and the
SpamBayes project, which has an MS Outlook extension (COM control) that puts
up it's own setup and management dialogs written in Python-MFC. I think that
if you use the appropriate COM interface(s), you can build an active-x
control to embed into Excel in the same way as a VBA control.

You can find Spambayes at and it sounds
like you already know about PythonWin.
