Converting C Applications to PHP functions/classes?

Hey All, I'm new to the php-dev list...so please be gentle! I did try searching through the php-dev list archives, but the search terms I could think of were way to generic. I'd like to take a C application, and convert it to a PHP Class or function. However, I'm not much of a C coder, and I'm a relative PHP beginner (only been using it for about two years.). Is there any such thing as a "c2php" converter? I know that probably sounds crazy...but... I understand that if there were such a thing, it would still mean work on finishing the port. Specifically, I'm looking to convert the "ipsc" (IP Subnet Calculator) program into PHP function/classes. I'm working on a "network and IP hosts" management program in PHP, and don't want to rely on calling 'ipsc' as a system command, then parsing the output (which I've done successfully...). It's slow and prone to error, and other problems. Any and all help is greatly appreciated!! v/r Shane
