Here's working example in C. Should be easy to adapt.

#include <gtk/gtk.h>

gboolean timeout_cb (gpointer dialog)
{
	static gint countdown = 10;

	--countdown;
	if (countdown > 5)
		return TRUE;
	if (countdown > 0)
	{
		gtk_message_dialog_format_secondary_text (GTK_MESSAGE_DIALOG (dialog),
"Timeout %d", countdown);
		return TRUE;
	}
	if (GTK_WIDGET_HAS_FOCUS (gtk_window_get_focus (GTK_WINDOW (dialog))))
		gtk_widget_hide (dialog);
	else
		gtk_dialog_response (GTK_DIALOG (dialog), GTK_RESPONSE_REJECT);
	return FALSE;
}

int main (int argc, char *argv[])
{
	GtkWidget *dialog;

	gtk_init (&argc, &argv);

	dialog = gtk_message_dialog_new (NULL, GTK_DIALOG_MODAL,
GTK_MESSAGE_QUESTION, GTK_BUTTONS_OK_CANCEL, "%s", "Proceed?");
	gtk_message_dialog_format_secondary_text (GTK_MESSAGE_DIALOG (dialog),
"%s", "Waiting...");
	g_timeout_add (1000, timeout_cb, dialog);
	switch (gtk_dialog_run (GTK_DIALOG (dialog)))
	{
	case GTK_RESPONSE_NONE:
		g_message ("%s", "Expired (timeout with no action at all)");
		break;
	case GTK_RESPONSE_REJECT:
		g_message ("%s", "Ignored (timeout with lost focus)");
		break;
	case GTK_RESPONSE_DELETE_EVENT:
		g_message ("%s", "Dismissed (window is closed)");
		break;
	case GTK_RESPONSE_OK:
		g_message ("%s", "Approved (button OK is clicked)");
		break;
	default:
		g_message ("%s", "Defaulted (any unspecified response)");
	}
	g_source_remove_by_user_data (dialog);
	gtk_widget_destroy (dialog);

	return 0;
}
