FrontPage was dropped by Microsoft many years ago. It was replaced by Expression Web (Microsoft), which doesn't require any server extensions to be installed. I have no idea what the upgrade path is, if you have been using FP.
There are many other HTML page/site editors available, besides EW, if you don't wish to learn HTML and CSS. Dreamweaver is perhaps the best known, but has a fairly high price. There are a number of free editors, and Lunarpages itself offers Page Mason (I think it's still offered).
