You need not anything else.  CGI program is actually very simple, it only requires you to read from the stdin/environment variables, and write output to stdout.  That's it.  If you are unfamiliar with CGI, first you'd better get a book to know what the standard is.  When you know the protocol, writing a program for it is a piece of cake.

In short, you need to get the envrionment variable "CONTENT_LENGTH", the read from stdin that number of bytes, which takes the form of "name1=val1&name2=val2...".  Then you need to a procedure called "unescaping", which means to convert al the "+" to " " and "%xx" to its ascii value.  Now you get all the information sent to your cgi and need to write whatever your output to the stdout.  It must starts with this:       

printf("Content-type: text/html\r\n\r\n");

However, you may need a web server on your desktop so that it is easier for your test, then I suggest you download a free web server from the net (I myself is using microsoft personal web server)

Hope this helps
