Don't know a magic all-in-one program, sorry. But it really isn't hard as long as you burn the image in the right format.
You will need a licensing tool to make the disc bootable. Something like HitLice (http://hitmen.c02.at/html/psx_tools.html
) would do nicely.
If you've already got the SYSTEM.CFG file from the damaged disc and the all the data files then it should be easy.
