I've been trying to find a CMS that handles more than one language. We have WebGui installed but it doesn't handle languages as far as I can see. We have very basic needs as far as other functionalities goes and I'm actually thinking of coding a simple content manager myself. But I thought that I should ask here first.
What languages do you need? Most of the CMS systems I've seen handle multiple languages. It will come down to which CMS systems handle the rest of your functionality needs. You can use something like the CMS Matrix to find which CMS systems meet your needs. In this case you would probably want to check the boxes for 'Multi-lingual Content' and 'Multi-lingual Content Integration'.
