The GtkAdjustment associated with a spin button always holds the value
of the button, since the value of the adjustment *is* the value of the
button. So, you should create the GtkAdjustment first, and then create
the spinbutton. 

    GtkWidget *adj = gtk_adjustment_new (...);
    GtkWidget *spin = gtk_spin_button_new (adj, ...);

whenever you want the value, just use the adjustment.
