All you have to do is this:

/* Create the integer data model */
GtkAdjustment  *adjustment = gtk_adjustment_new (...);

/* Create the "dial" view for the model */
GtkWidget      *dial       = gtk_dial_new (adjustment);

/* Create the "spin button" view for the model */
GtkSpinButton  *spin       = gtk_spin_button_new (adjustment ...);

Add them into a container... since they share the same adjustment;
the values will always be correct (no need to create fancy
derivatives for this simple case ;-p ).
