CGI.pm is still around and you can use that if you like - it will be fine for a low-traffic site. However it does still come with all the old HTML-generation functions (for backwards compatibility) and those are pretty much universally frowned on these days. I still create some sites using CGI (the protocol) but in most cases use one of the less heavy alternatives like CGI::Lite, CGI::Minimal, etc.
If you are expecting it to be a high-volume site then something with a persistent back-end is going to be a better bet and there are a whole heap of options in that space, including using an FCGI wrapper around plain CGI scripts.
