[python-win32] Can't catch WM_CREATE

The problem is the way win32gui works.  win32gui sub-classes the created
window *after* the call to CreateWindow returns - however, WM_CREATE is sent
*before* CreateWindow returns.  It may be possible to rework win32gui to
solve that, but I doubt I will do it :)
