There is no package that will automatically go from schematic to PCB, but there are plenty that will make the process of designing a PCB easier. Google for the word "EDA" (electronic design automation). There's hundreds of tools out there, unfortunately, most cost thousands of dollars. However, a number of cheap and free ones are pretty good. For strictly PCB design, Eagle is the choice of many, the light version is free and lets you work with PCBs up to 10cm x 8cm.
