Put this on a bootable usb with ubuntu or something and run it against the drive in question. Let it run overnight, and in the morning, you may find yourself with a windfall.
After it runs, it will create a wallet.dat file that you will load with bitcoin-qt. If it works and you have the private keys, I would recommend exporting them into a better format, like an electrum or armory wallet.
If you didn't shred the hard drive and haven't defragged it or anything, there's a good chance that the private keys are able to be recovered. There are scripts that will scan a drive for fragments that look like bitcoin-qt wallet files and dump the keys.
