Please point me in the right direction

Hi All, I have a CGI application written in Delphi web services and I want to port it to the Linux environment. I was going to use Kylix but I'm concerned that Borland isn't keeping up with the fast paced Linux development (ie they are still on Redhat 7.2 and Redhat is about to release version 9.0 next month). The current CGI is a little complicated and relies heavily on OOP data structures. It processes the data then sends a stream to the web server for display in the browser. It's very fast and I am happy with the performace, but I must port it over to Linux. As I am very unfamiliar with the PHP environment, can someone point in the right direction? If I use PHP for the front-end, what is the best tool to create the CGI? I was considering using Python, but would Pearl be better? Any direction to get me started and headed in the right direction would be very appreciated Thanks, Jerry
