Creating pages to translate

I'm writing lots of public freeware Windows applications and I would need translation of the interface texts and language files... German and English is okay, but other languages, as for example Spannish, Frensh, Russian etc. are problematic. I am spending very much work in MediaWiki and translatewiki (recently), so I wanted to ask other people to help me a bit ;)

Ah, and by the way: Most of them are Open-Source. Not all, but there are defenitely no commercial projects planned (as far as I remember).

If you are talking about new software to be added here, Special:MyLanguage/Translating:New project has an overview how it happens.
