Brainstorming - Teamspeak PTT Bluetooth Device Answered

Gurus of the Tech World,

First off, I'm browsed through a lot of great idea and I've got to say, you all are geniuses.  Hopefully, someone can help steer me in the right direction.  I have made a few Windows Phone apps, made a few HTML websites and some networking fundamentals, but I've never really made a device... much less soldered a board.

With that said, I want my first project to be a Bluetooth Push-to-Talk (PTT) button for Teamspeak.  I have a Bluetooth headset with a microphone for Teamspeak (VOIP PC Application) so I can hear people speaking while being away from the computer but I do not have a way to communicate back using the Push-to-Talk method.

So, what I want to do is make a small Bluetooth device, maybe powered by a 9V, with a single PTT button, and maybe an ON/OFF switch to save power.  My thought is to program it so that it send a keystroke to my computer for the duration that the PTT button is pressed (CTRL would be ideal).  This is something that I want to make, using as much of my brain as possible and the least amount of prefabricated merchandise ("omg, just buy a bluetooth dongle and plug it into a button. ta-da").

I'm sure that this is something you guru's can do blindfolded, but, please, point me in the right direction... and use baby words.

Thanks!
