I haven't heard of PHP, can you point me in the direction to get more information?
Well, obviously you can look at the PHP Website
, but there are a million tutorials online to get yourself started (and hundreds of books). It's not hard and you'll find a lot of people being able to help you. There are several newsgroups for PHP in various languages.
Regarding Frontpage: If you already own it, you might give it a try. Otherwise you better avoid it, as it usually produces some really bad markup (especially if it's an older version). The main problem is IMHO, that it offers so many useless "convenience features" to make it behave like e.g. Word or Pagemaker, while HTML markup is something different.
OTOH every one of us has to create some kind of "my first website" to look back at and shudder in disgust after a year or so
. So start out with Frontpage until you reach it's limits, then throw it away and learn HTML coding. Or just start out with that and don't bother with Frontpage. If you really need some kind of visual help, you can check out Mozilla Composer oder the split-off NVU
But don't expect too much from any of those pseudo-WYSIWYG tools, as they tend to bloat your markup. If you write it with a good editor all by yourself you can be concise and focused on structure and content. That not only sounds good, it gives you nice things like "easy maintenance", "scalability (it works on your cellphone as well)", "short loading times", "compatibilty" etc. - it's simply better.
