hard disk wiping...

I've recently decided I would like to make my own distro, just to see if I could. I was talking to a bunch of my friends, and one of them thought it would be cool if the distro contained, as a prebuilt/installed program, a hard disk wiper that wiped the /home partition and left the /~ partition, where the OS is, alone. I would absolutely hate to have to learn C from beginning to end to do this, since it would take me quite some time that I don't really have, so I was wondering if anyone knew of a native program that did the same thing. I know that in a terminal, I can type 'shred -vfz -n 100 /dev/hda' and that will supposedly wipe the hard drive, but I don't know if I could create a GUI for it in the system menu of my distro, also if I could create a warning before it implemented the wipe. Bear in mind that I've only been using linux for three weeks or so. I've decided to do this because I have no truly intellectually stimulating activities any longer. My jobs are mind numbing. Could I type '... -n 100 /dev/hda6' to specify the partition I want to wipe, hda6 being my the device name of my /home folder on my computer now? I know ambitious is nowhere near the word to describe this goal, but I'm going to do it eventually, even if I have to learn C from scratch and write everything myself.
