it would be easy but no, because wxPython is not a pure Python library (only
with Python files). It use wxWidgets (C++ library)

The Mac OS X version, for example, is only available in 32-bit mode because 
WxWidgets probably uses Carbon library, which is not available in  64-bit
mode. "This, in turn, means that using it in Python requires you to launch
Python in 32-bit mode (Python is a universal binary with both 32-bit and
64-bit versions of itself available in the same binary file, so it can be
launched in either mode) from

If you look at the downloads of the binaries of wxPython, there are also
versions for Windows 32bits, and Windows 64bits for example

It may be that the problem, but if we don't know the error message...
