You can specify an accelerator when you add the action to an
ActionGroup:
http://www.gtkmm.org/docs/gtkmm-2.4/docs/reference/html/classGtk_1_1ActionGroup.html

You should not need to create an AccelGroup manually, but if you have
some need for that, I can find out how that works.

There's more here on the basics here:
http://www.gtkmm.org/docs/gtkmm-2.4/docs/tutorial/html/ch11.html

I think, you can also specify the accelerator in the UI definition.
That's mentioned here, though the format is not clear:
http://developer.gnome.org/doc/API/2.0/gtk/GtkUIManager.html
