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:
