no contemporary hardware should have any problem reaching that
framerate at that resolution, even if you stick to standard "blit" inter-
faces.

getting the data into the "blittable" object fast enough may be more
of a problem, though.  I don't know how good wxPython is in that
respect; Tkinter's PhotoImage is probably not fast enough for video,
but a more lightweight object like PIL's ImageWin.Dib works just
fine (I just wrote a test script that reached ~200 FPS at 1400x900,
but my machine is indeed a bit faster than a 1 GHz Celeron).
