The new open sourced mod_coursecertificate from Workplace allows for basically the same behaviours as what Beatriz described, but in both scenarios you have to consider whether awarding a badge or certificate is the appropriate instrument.
The badge approach is, IMHO, an elegant solution and not as heavy as awarding a certificate. You'd send your participants a 'Course Completer' badge with some additional text in the description.
