i am confused. since g_object_new cannot possibly instantiate a C++
object, what is the value of get_type() returning a value that can be
used at the C level?

you can't create C++ objects (the ones that gtkmm is composed of) from C
without a *lot* more glue code (eg. factory functions declared extern
"C" that return each type of object as a gpointer etc etc)
