This function works recursiv. So you could work with maybe the main dialog
widget. Define this widget static for this file you are working with maybee
like this :

static GtkWidget *main_window;

int main()
{
..
main_window = gtk_window_new(..);
more to come ...
..
} 
Now you could use get_widget with main_window and the widget name you give the 
other widget .... 
Hope this helps otherwise mail back and i`ll send you the whole pice of code ;)
