219808 Shopping cart 1 click install

I want a script, with web user interface. The script is to install OSCommerce, OSCommerce MAX, CRE Loaded & Zen Cart. This is to be a 1 click install, much like fantastico that comes with Cpanel (this script i want made has NOTHING to do with cpanel, it is completely stand alone) The only thing the end user will provide is the choice of directory to install into (this must be validated to make sure it is not already take by another user) and any other commmon questions asked during install of each cart. This script is NOT to ask questions of the end user about databases etc... much the same way as fantastico does.
