( (NoteBookLabel *) get_tab_label( some_child_widget ) ) -> label
this should give you access to your label (maybe you need to make it
public or use an accessor function, but you get the idea )

But i'm not sure if this is the way to do this. I see you keep a pointer
to the child widget in your NoteBookLabel, why is that?
(Formularies *form_ptr; //the widget that is the "body" of the notebook
page)

I've build this kind of labels before (he, we all did) and never used a
special class for them. Just put the button and the label in an hbox en
add it to the labelspace. Maybe a function would be more appropiate? (
Gtk::HBox Get_Label_Widget( const Glib::ustring & label_text ) ....

this way you can set your labels bij doing:
append_page( child_widget,  Get_Label_Widget( "blabla" ) ) ;

Anyway, i hope this will help you a bit. :)
