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;
}
