Hello lolaSDG,
Welcome to the forum! This is a good question for a first post.
You shouldn't have to create two categories for each language. You can do a lot of the translation with language packs and language string overrides and custom language files that you create.
A couple of extensions might also make things easier for you. Joomfish and Faboba will be very helpful.
Check out these tutorials we have.

Cheers,
