You can probably pass the widgets you need to reference as arguments to
the functions in util.c that need them (if they are too many, make a
struct with pointers to them, and pass that)

You should consider _not_ using glade to generate code, but using
libglade instead. There are many reasons for this (cf., for example,
<http://lists.ximian.com/pipermail/glade-devel/2003-February/000015.html>)
