gtk_accel_group_attach() is an internal function,
use gtk_window_add_accel_group() instead.

keep in mind that the GTK_ACCEL_*VISIBLE flags are only evaluated
if you are using a GtkAccelLabel, e.g. instead of creating a
button with an ordinary label:
   button = gtk_button_new_with_label ("Quit");
you'd create it with an accelerator label:
   button = gtk_button_new ();
   label = gtk_accel_label_new ("Quit");
   gtk_widget_show (label);
   gtk_conatiner_add (GTK_CONTAINER (button), label);
   gtk_accel_label_set_accel_widget (GTK_ACCEL_LABEL (label), button);

then GTK_ACCEL_VISIBLE and GTK_ACCEL_SIGNAL_VISIBLE will actually
take effect (the accelerator bindings for the button are displayed).
