I'd do the following
1. choose a storage option for your content (you may want to use a simple
table with a 'text' field for editing online, or code something to save the
content to a "txt" file)
2. code something that inspects the uri_language and does
(semi-programming-language):
if exists "nameoftherequestedarticle":
if uri_language in "translationsofthearticle":
content = translatedarticle
else:
content = originalarticle (english ?)
else:
raise 404--
