Very good.

Have a look at the existing cutecash code: In 
src/optional/gtkmm/gncmm/Account.hpp there's an gnc::Account, and as you see 
there, the module has a gnc::GncInstance base class that wraps the QofInstance 
"object" that manages the qof parts. This in turn is derived from Glib::Object 
which is the C++ version of a GObject.  In my opinion, this wrapping of 
GObject and also (while it still exists) QofInstance in the end looks very 
well possible and the resulting C++ classes look well enough like a real C++ 

Disclaimer for all other readers: The C++ part of this discussion is currently 
only an academic one. It has not yet anything to do with the real work that is 
done in the coming months.
