I'm not sure if tongues is something you can learn from other people. It's a gift from the Holy Spirit and He gives them out as He sees fit. I can't do it though and have never heard anybody do it in person, so I could be wrong.
As far as if it is real or can still be done today, that is a personal opinion for everybody. It just sounds like babbling if you don't have somebody to translate it for you, which is a different gift of the Holy Spirit. Paul tells us in 1 Corinthians 14, starting around verse 6, that if we don't have a translator nothing is really being accomplished.
[Edit] Also, I should say that some people consider it talking in a fake babbling spiritual language, while other people consider it being able to speak in languages other than your native one, without any teaching.
