If you want fast and easy,  google WinQCAD.

It outputs gerbers and CNC files.

Probably the fastest to learn, espically as compared to Eagle.


But, it will not win any Olympic medals.   There are many programs 
that will out-do it, but it offers all the basics.

Another one to look at is TARGET.

The toner transfer is the easy way to do it at home, but be careful 
about the learing curve.  you will waste some boards.

Double sided is easy if you align the marks on the papers and then 
slide the board between.

Drilling is best done with CNC, and if you have not done some, 
considder two approaches.

#1, use only 0.1" pin spaceing.  Then buy a perf board and use that 
as an alignment for drill holes.

Or, buy a machine tool socket and drill out all the pins.  then drill 
Pin #1 on your IC, then insert a blank drill and the drilled out 
socket and presto ! instant alignment.
