Basically what you want is to expose your class and say that one of its base
classes is defined in Python. Right now, Boost.Python does not provide this
functionality. In some cases it is possible to create work-around to the
problem, but I am not sure about your use-case. Take a look on next link
http://www.language-binding.net/pyplusplus/troubleshooting_guide/exceptions/exceptions.html-
it contains solution to similar problem.

P.S. Python-Ogre project, exposed using Boost.Python, makes an extensive use
of wxPython. May be they have some knowledge or "ready" solution for you.
