I did the same thing in the component manager. In the git repository for the 
component manager, there are the following sources:

geom-* : Boxed types representing all the primitives.
sch-*  : GObject types representing all the GOBJECTs in gEDA.

These portions of the code are decoupled well, and anyone is welcome to use
them.

I discover that it is quite easy to burnout with the large amounts of
boilerplate code required by GObject. (I also discovered that Vala takes
the pain out of implementing GObjects.)

Cheers,
