This is really a strange hack :)

Remember that GTK+ is a widget library. You can allways
create an empty dialog, a container and then add the
needed widgets to this container. **pseudo** code should
look like that (sorry, I'm not a Perl guru :)

dial = dialog_new
c = container_new
dial.add(c);
do n times
  w = widget_new
  c.add(w)
end do

You may have a look to any existing perl-gtk+ program
to get the right syntax.
