Just an idea: are you sure that your widgets have the right event mask ?
If you want to catch mouse clicks you have to connect to 
"button-press-event"
signal and also call gtk_widget_add_events() function with 
GDK_BUTTON_PRESS_MASK
as a second parameter.
Consider:
http://developer.gnome.org/doc/API/2.0/gtk/GtkWidget.html#gtk-widget-add-events
http://developer.gnome.org/doc/API/2.0/gtk/GtkWidget.html#gtk-widget-set-events

You also can take a look at examples coming with gtk like 
"scribble-simple" and "eventbox".
