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. */
}
