[Plugin: Custom Contact Forms] Multilingual Contact Forms

I am trying to integrate this contact form plug-in into a multilingual site (qTranslate). Sadly, after testing, I realized that it doesn’t integrate with qTranslate. This is OK I suppose, and I decide that I could merely create a distinct Contact Form for each language.

The problem arises when I wish to insert a Captcha or emailAddress field (for instance), because even if I replicate the field settings/options, the validtion do not work.

So how can I assign e-mail validation to a field with a slug fixedEmail (for example)? How can I assign a Captcha to a field captcha field named captchaFr (for example)? Or is there a better way to approach this alltogether (I am open to ideas)?
