Yeah.  C applications usually create a popt table and pass it to
gnome_program_init via the GNOME_PARAM_POPT_TABLE property.  If init
sees --help, it prints out those options under "Application options",
and all the library options after that.

Couldn't you just print your help stuff here and call
Gnome2::Program->init nevertheless?  That would come quite close to what
the popt table stuff does: the application options are printed first,
followed by the library options.
