You mean in the edit grid as selectable values? Sure, go for it.

wxComboxBox would seem more appropriate - list boxes are not really an
appropriate control from a UI perspective. You will need to give some
though to how the data will be populated, especially when there are a
lot of rows on the child table. I would consider using a single source
of data for each column, and maybe list 50 rows at a time, but add a
pseudo-option as the last item which, if selected, will grab the next
50 rows. Use a cursor to get the data (might be a good time to think
about adding cursor support to pgSet), and cache it so we only have to
get it once when the form is loaded.
Sounds like a fun little project actually...
