Old versions of wxPython ("classic") used SWIG to wrap the C++ libraries,
and could be compiled with PyPy. It worked, but it was a long time ago, was
the result was quite slow...

(unfortunately the screenshots are lost)
Newer versions of wxPython ("Phoenix") use SIP to wrap the C++ libraries,
and there is no way it can be supported directly by PyPy (SIP uses
metaclasses with custom tp_alloc slots to subclass int... I tried).
There was an attempt to port have SIP file generate a cffi interface, it
did not go to completion but looks very promising.
There is a nice story here: http://waedt.blogspot.fr/
It seems that all basic infrastructure are there, but many widgets extend
SIP wrappers and use the C API: they need to be rewritten in a
cffi-friendly fashion.
Good luck with wxPython.
