Both of your ideas seem sound to me. You could also look into using
statically assigned IDs that increment by one. Then you could just
increment or decrement by one and look up the field by ID. Of course,
that might get ugly and there are some IDs that are supposedly
reserved. But it's an idea.

Also, I've heard that Dabo (http://dabodev.com/) is good for database
work. You might look at that. To get the quickest and most on target
answers to wxPython questions, I recommend the wxPython users-group
mailing list: http://www.wxpython.org/maillist.php
