Of course. GTK+ is all about signals and callbacks. The following code
should work:
[construct GUI here]
gtk_timeout_add (1000, print_number, NULL);
gtk_main ();
and would call function print_number() every second.

Using multiple processes is sometimes necessary, but can be avoided for
most apps.
I think you should start by reading the GTK+ tutorial on www.gtk.org. It
explains signals and callbacks in the first chapters and goes into more
detail (idle functions, timeouts) somewhere around chapter 18.
Salut, Sven
