Well, then

a) static: you likely have some structs (GObjects) that hold the GUI so
just add the page widgets there.

b) dynamic: after creating a new tab do

g_object_set_data(G_OBJECT(notebook), 'tab-misc', page_widget1);
g_object_set_data(G_OBJECT(notebook), 'tab-unsorted', page_widget2);
g_object_set_data(G_OBJECT(notebook), 'tab-other', page_widget3);
g_object_set_data(G_OBJECT(notebook), 'tab-stuff-that-does-not-really-belong-anywhere', page_widget4);
etc.

and then retrieve it with
page_widget = g_object_get_data(G_OBJECT(notebook), 'tab-misc');
etc.

c) with desctruction: if tabs can be also destroyed by the user you have
to connect to the notebook signals (or the page widget signals) and
manage the connection.
