I am looking to have a cms which lets users to write a post in 5 different languages, side-by-side (in 5 columns by the language name at top and the text at buttom), editting the post sould be limited to editors. It must be very simple to use, archive, search has to be on place. Is it possible to amend any ready to use cms scripts to acheave this? I do not want to use complicated cms and plugins and themes, one admin area, edit page and front page is enough.
You can use and tune free Joomla! with Joom!Fish CMS or Drupal, even Wordpress, there are a lot of extensions allowing to use several columns and many languages.
