As I know multilanguage development/maintainance is a not-so-easy task, can I suggest a good way to go?
Use GNU Gettext as the foundation for translations, and "pot/po/mo" format.
This way a good po editor could be used (e.g.
poedit, which is multiplatform).
And let the community help to speed up things.
