I should note that Fred McLain has made the argument that the GUI
ballot application should eschew the use of widget libraries such as
wxPython of PyQt. He mentioned this on the telephone, and in email;
I'm not sure if that email went to the OVC-Dev list, or just to a Cc:

The current GUI app was designed and written by Jean-Paul Gignac using
a library called PyGame. This approach basically takes a fixed image
of the ballot for a background, then responds to clicks in certain
regions of the screen. This bypasses the use of high-level widgets
like radio-buttons or pick-lists.

David Jefferson's security concern seems to promote the continued use
of a similar programming style to that Jean-Paul and Fred chose.
