It seems I said it bad so was misunderstood. Sorry. I meant not
global shortcuts for global operations but rather global configuration
of shortcuts for applications, such as 'Copy', 'Paste', 'Reload', etc.
Instead of hardcoding them or having some own configurator in every
application - to have them configurable by common tool. You know, KDE
hotkeys editor also has different tabs for that - one for globals and yet
one for applications. But still it's in one tool for all applications.
And I'm talking about that, not global hotkeys.

That's correct!

Ouch, that's a lot really. But most of that could be simplified just
knowing gtk_accelerator_parse() accepts char * so the config can be in
plain text with keys defined as (for example) "hideall=<Ctrl>h,<Alt>F12"
and library will just parse and fill caller's array with such texts which
will be eaten by gtk_action_group_add_actions(). I think the Qt has some
similar methods too. And I think of that library as something very simple
not bound to Gtk, Qt, or whatever at all. And of course, it is possible
to write a Gtk+ widget over it which will implement what you've described
above.
And anyway I've asked not about implementation yet but about the
idea to have configured it in common tool. But I cannot see if you like
it or not. From what I see you want still each application to have own
keybindings? And if I want to set 'fullscreen' key to be F12, I have to
set it in each application if that application decided to implement the
dialog and is written with Gtk+ support, right? And those that aren't
will have it hardcoded still... I don't see much reasons why I would use
it, may be only to correct too different bindings which some application
might have but it's rather rarely and as developer I don't see much of
advantage but I rather would prefer the KDE way where I set it in some
keybinding editor once and for all applications.
