As far as I know, that kind of setup is only possible with PHP. There might be some way to fenagle it with javascript that reads the text as a source, but its probably more trouble than its worth.
If its just a simple site, I'd say try
blogger, and format your news page to match the rest of your site.
Its as simple as inputing your FTP info, building a simple template, and then publishing through blogger. I also like it because anyone with a blogger ID can be added to my community and be allowed to publish news.
