Building a simple long desk/bench
Another very simple 'desk' to put together is using a piece of wood the size you mentioned (for the desk top) and any two large objects to put underneath the desk top, separated enough for you to fit a chair between them.
For the desk top, you may be able to find a short piece of counter top at Lowe's fairly cheap. I've seen people use a flat door for this also.
To support the desk top, I've seen desks using two filing cabinets of equal height, two iris carts, saw horses or anything you can find two of that will be the proper height to put under there, as long as they are sturdy enough.
Willie T is right about building a desk without knowing some of the basics. In the long run, you'll likely spend more money than you need to and end up with an unsafe desk that you won't use. Glue alone will not hold the pieces of wood together.
Parsec's idea of getting one at Ikea is probably the best thing to do.
You can also look at second-hand stores, yard sales, Craigslist. I see them ALL THE TIME on Craigslist.com for free. But be careful if you're going to someone's home to get it, take someone with you just to be on the safe side.
