Actually, there is not really any such thing as a "real togglebutton"
in GTK+.

GTK+ basically has 

 "check buttons drawn as toggle buttons"

and:

 "radio buttons drawn as toggle buttons"

It turns out that there are two ways to do the former - creating an
instance of GtkToggleButton or a instance of GtkCheckButton with the
"draw_indicator" property set to FALSE. But that's just an artifact of
a silly design choice -- the fact that there is GtkCheckButton _and_
GtkToggleButton really doesn't make much sense.

The primary use radio buttons drawn as toggle buttons is tool palettes
(and also possibly toolbars.)

While using a radio button group across multiple pages of a notebook
sounds really bizarre, I think UI-wise it should be OK for a 
multiple-page palette. But if it doesn't work easily, I'm also
not too concerned if you have to use multiple radio button groups
and synchronize them.
