Why not use GLib GObjects? Well, in the narrowest sense, QOF already does: 
there is a QOF to GObject glue layer, and GLib GObjects (including GTK 
objects) are searchable with QOF. More broadly, the problem with GObjects is 
that they don't support unique object id's, and they don't support 
versioning. Now, I suppose we could build those on top of GObjects ... and 
maybe we will someday. But QOF evolved in parallel, independently from 
GObjects, and thus there's overlap of ideas. Parts of QOF date back to 1997, 
and thus the parallel evolution is in part because GObjects didn't exist back 
then. Maybe there might be some convergence, maybe, someday.
