I hate to say it, but usually when something like this happens it's most likely to be hardware related. If you don't have access to a spare, go to a T-Mobile store and ask to borrow a battery to see if it'll power up with a known good one. Batteries usually don't just die like that, but it can happen.
So you don't get a short vibe or anything out of it? What about when you hold the power button for about 10seconds? If you remove the battery and plug it in, do you get an led lit up? How about with the battery in?
If the battery turns out to be good, you could attempt the debrick method by KAsp3rd stickies in development. I don't see why it would be a brick, but at this point I'd try anything available just to be positive.
If you have insurance on it, it may be time to consider using it.
Sorry to hear this is happening to you man. These S3's are starting to get a little old though, and no matter how careful we are, they do suffer more abuse than any other electronics we may use. I'm seeing more and more posts like yours recently, I'm sorry to say.
Keep us updated on it, and good luck with it!
