I took a random language on rasonator :
https://tools.wmflabs.org/reasonator/?q=Q14560&lang=bi result : everything seem to be in english ...
That's for the translation of simple terms. I have pretty much no idea of the grammar of that language. If youwant to generate a simple sentence "subject, verb, complement" you need a model of that language, which is probably a reasearch subject for linguists. I think it is simpler to find a user who talk this language and let him team up with a wikitemplate programmer than to build a software that is aware of the grammar of a lot of languages, with a formal model of the grammar and so on :)
But I admit this is disputable :)
