Do you mean you want to build a multi-lingual site? You can certainly do it manually, but if you are looking for a software option take a look at Transcribe.
Also, I just stumbled across this article which looks very helpful.
Another option is Publisher. I’ve used both Transcribe and Publisher and my preference goes to the latter both in UI and performance, nevertheless Transcribe is also a good addon that may be suitable to your needs.
