How to use IMessage on a PC?

I would look into this myself, but really don't have the time. Is there a way to somehow send iMessages from a PC? I love my iPhone and would love the ability to text from my laptop but will never switch from PC to Mac (wouldn't make sense to as a Comp Sci major) any ideas?

. A quick google search indicated you could jailbreak your iPhone. I have a macbook and I really don't even use iMessage on it. Not that it isn't handy at times, but it isn't a big deal to have it pushed to your computer.

There's a Mac version but not a Windows version.
