gtk_label_set_text(GTK_LABEL(somelabel), car *newtext)

Try the gtk_widget_get_toplevel() or some similar call.  I can't remember
the exact name of the call.  Here's a way to "cheat" that I used before I
knew how to do this myself...

GtkWidget *get_widget_window(GtkWidget *input){
	GtkWidget *foo = input;

	while(foo){
		if(GTK_IS_WINDOW(foo)) break;
		foo = foo->parent;
	}
	return(foo);
}

Watch out for this returning NULL.  I haven't tested it much, but it
should work.  It will stop when it hits a window that is a parent of the
widget you passed in.

Hope it helps.
