How to make a simple wireless digital communication circuit?

Hey, i want to make a simple wireless digital communication circuit. This is not exactly what i'm going to do, but this is the easiest way to explain it: watch the image below. What should i build inside "box ?(1)" and " box ?(2)", to make the 2 LEDs turn on when i push the button? The first circuit should be like a transmitter and the seconds one a receiver, but i just don't have any idea how to make this simple circuit. I don't really know what frequency it should be at.. What's the easiest to make and works for the longest distance without problems with background radiation?
(I'm sorry if this is a stupid question but i really a noob in hardware development... :p )
Thanks for helping!

For a few $ you can buy just what you want. A lot more reliable and certain to work.

There are many variations on the Xbee generally intended to operate with low cost microprocessors.

Could something like these cheap ones work without a microprocessor and just fit in those boxes, or is one absolutely required?

This is an easy question but hard to answer. on balance I would say because you lack experience the easiest way would be to use something like the Xbee and a Picaxe 08M microprocessor. The cost of the Micro will be about $2 (£1:80)

Programming will be easy as their site has examples.

To build something that can drive data into to these units will be as complicated for you as making a radio Tx RX.

This is the data sheet to give you some idea.

As you will see you can drive them with switches but that may not suits what you need.
