how to use atkmm

[Antonio Coralles <noche suapie reflex at>]

i've now spend some time looking around in the dokumentation for 
namespace atk and what i found there really made me curious. but there 
are two little problems which prevent me from playing around and getting 
familiar with the library:
1.)     i didn't find out how to obtain an instance of the various 
objects in namespace Atk, except from using wrap(...)
2.)     i also don't know how to add atk-objects to a widget (for 
example a Gtk::Window)
it would be nice if someone can give me a hint .... i hope i haven't 
missed something too obvious in the documentation :-)
thanks,
            antonio
