Your question is not clear, what do you mean by "widget"?  However, what
you probably want to do is pass a pointer to the widget as the final
argument to g_signal_connect() when you hook up the callback to the OK
button.

A snippet of the main function would be:

GtkWidget *widget;
GtkButton *button;

/* Create the widget, button, and other stuff as required */

g_signal_connect (G_OBJECT (button), "clicked", G_CALLBACK (ok_button_cb), widget);

gtk_widget_show_all (widget);
gtk_main ();

And the callback would be:

static void
ok_button_cb (GtkButton *button, gpointer data)
{
	GtkWidget *widget = GTK_WIDGET (data);
	
	/* Do the things you want */

	gtk_widget_destroy (widget);
	return;
}

Just add another page to the notebook for each tab your user needs.  You
can either prepend or append:

http://developer.gnome.org/doc/API/2.0/gtk/GtkNotebook.html#gtk-notebook-prepend-page

http://developer.gnome.org/doc/API/2.0/gtk/GtkNotebook.html#gtk-notebook-append-page

All of the functions about notebooks can be found:
