You're the first person who has asked, but yes, it would be possible to
modify the Python wrappers to pass a Qt object as the callData.   If you're
willing to try, or if you know someone who'd be willing, I'd be glad to
provide assistance.  The modifications would have to be done in
vtkWrapPythonMethodDef.c.  The wrapper API provides a method
called SIPGetPointerFromObject() in vtkPythonUtil.h that is specifically
made for getting a "void *" for a Qt object.
