OK, without regard to the UI goodness or badness, if you want to do
this, use radio buttons and:

void       gtk_toggle_button_set_mode          (GtkToggleButton *toggle_button,
                                                gboolean         draw_indicator);

Please don't try to emulate radio button groups yourself.
