Please can anyone show me an easy- to- use PCB software that can

There probably is nothing that can do a reasonable job of
"automatically" creating a board layout, given just the schematic (but I
could be wrong). However, there are packages that have schematic capture
and board layout components that work together to assist *you* to create
the layout.

KiCad http://kicad.sourceforge.net/wiki/index.php/Main_Page and gEDA
http://www.gpleda.org/ are each free, open source suites with schematic
capture and board layout.

KiCad has a reasonably active and supportive user community and is
available in versions for both Linux and MS Windows. The principal
author's homepage is over at http://iut-tice.ujf-grenoble.fr/kicad/

I'm less familiar with gEDA. As far as I know, there is not an official
MS Windows distribution available. DJ Delorie may drop by with more
info, though...
