I think, the question is understood different. Luben111 is refering to auto placement and auto routing software. But particular the auto placement feature won't be of any use for a beginner. And the result of single layer auto routing without well considered placement is rather questionable. I really appreciate the performance of the Specctra router, but I won't suggest it for any one without some years of PCB design experience.
Any PCB design tool will in fact convert a schematic to a PCB, but need the user to perform component placement and either routing the traces or to define the rules for auto routing.
