Creating the interface by interpreting a dynamic form will
always take more time than creating it with procedural compiled
instructions.

But there are reasons why we dropped code generation
from Glade, rebuilding your interface in the future will
be tricky if you use generated code for instance - as specially
if you make the mistake of mixing in any (or too much) of your
code with the generated code (meaning you will have to possibly
"merge" in your UI changes in the future, even when keeping this
to a minimal it can represent a hassle).

Currently I really doubt that the performance of GtkBuilder
is going to be so bad on an embedded platform that you're
going to want to go through all this hassle of creating a code
generating and then dealing with merging in the code periodically.

I would suggest first to find out if it's worth your time by at
least trying out GtkBuilder with some random interfaces
on your device (and keep the xml in a const char string[] of
course to avoid the needless disk access).

Err what could you mean by that ?

Excuse if this is a misplaced suggestion, but there are tools to aid with
the generation of database applications too; have you looked at Glom
for example ? (http://www.glom.org/wiki/index.php?title=Main_Page)
