Take a circuit that you know reasonably well, design it in Eagle PCB or Express PCB.

Make a schematic file, make a board file

 

Chemical etching:

print the board file, you can use ferric chloride to remove the unneeded copper, leaving just the connections you need.

 

Milled pcb

make the board file, send to micromill, remove unneeded copper, leaving just the connections you need.

 

PrintedCircuitBoards has a few ways to make your own circuit board.

 

Here is some info on Eagle:
