php, just plain html ?
You'll almost certainly need ability to run php/perl/some sort of script on your website, unless you can find a friendly java applet to do it.
A quick search on google for "nntp in a web page" (nntp is the news protocol) gave the following:
After considering the above re: php, perl etc., take a look down the list of software at the section that says 'Perl' or 'Php' in the section heading on that page....it lists software that does what you want.
Hope this helps.
