You might want to look at:

That briefly summerizes the "binding" system for GTK+. 
The binding system is intended for doing things like
setting up keystroke bindings for Entry and Text widgets.

There is also, of course, the existing accelerator system,
which already allows runtime configuration of key bindings
for menu items. (Just press the key combination when the
entry is highlighted)

Neither of the systems allow multiple key sequences, of course,
and there is no builtin abstraction that would allow modifying
toolbars to activate menu items, so it isn't really exactly
what you are talking about with your commandapp. However,
there is enough overlap there that more comprehensive systems
should possibly be built on top of these facilities instead
of being put into GTK+ along side.
