Ok, almost figured it out but......

Ok, i've ALMOST got this. But just one thing..... : 

void
on_button1_clicked                     (GtkButton       *button,
                                        gpointer         user_data)
{
notebook1 = gtk_notebook_
        gtk_notebook_append_page (GtkNotebook *notebook1,
                                GtkWidget   *textview1,
                                GtkWidget   *untitled);
}

ok, im having trouble at:

notebook1 = gtk_notebook_

I don't know how to work this to get it to append the page correctly. If
someone could just tell me that gtk_..... command i'd really appreciate
it :)
