Feedback Device

Hi. I'm trying to build a feedback device that functions sort of like audience feedback system, recording responses on a database. I really have no idea where to start. The device will have five buttons and five corresponding LEDs. The device will interface with a computer program via USB. It is somewhat similar to the iClicker except it does not need to communicate wirelessly. Does anyone know where I might start on a project such as this?? Thanks.

take a few electrical engineering courses. Make sure they include computer programming and the USB protocol.

I've taken introductory courses to C, C++, and Java programming. I've also done several projects using the Motorola 9S12 microcontroller. I'm thinking of using an AVR or PIC, but I think that each may be a bit more complicated than I need for this simple task. Does any have suggestions on appropriate microcontrollers? The only stipulation is that it must have USB support.

Although this thread is over a year old, I think this sort of question is still worth answering.
For a lot of the questions/problems
For example:
How to communicate with a hardware
Feedback Device
6 Button PC Input
Interface between PC and a lamp switch

in this very cold part of the forum, Arduino could be the answer.
Google Arduino and you will see.
