So, where is the gwindow variable initialized ??? the device variable is
not initialized either ??? 

clearly, you should write something like:

static void 
clicked_cb (GtkButton *button, gpointer data)
{
        GdkWindow *win;
        GdkDevice *dev;
        GdkModifierType state;

        g_assert (data == 0);

        win = GTK_WIDGET (button)->window;
        dev = gdk_device_get_core_pointer();

        /* do stuff. */
}
