Martin, I can't think of any standard way to do this; the closest I know of from other Gtk+-ish software to declare such things in a machine readable format are jhbuild modulesets. Apparently, netbook-launcher is listed in the gnome-2.xy.modules jhbuildrcs.
I don't think jhbuild can install the proper build-dep packages for you, but it could at least build them from source for you.
