Does anyone know a good program that is easy to use to develop a website? Preferably for someone that does not know html etc .
Well, just for starters, if you don't want to shell out for Dreamweaver, you could try Nvu or FCKeditor. However, I can't tell you if either are any good, because:
a) I'm not a web developer, I'm a programmer, and
b) I thus don't have any problem writing HTML raw, which is normally quicker if you know what you're doing.
Depending on what you're doing, a wiki might do the job for you, which removes any need for learning HTML. However, if you use a CMS, which can allow you to vastly simplify a complex website, you may find you're going to have to learn HTML.
That's not a bad thing BTW. HTML is not like actually programming. It's like learning how to write a letter - there's a few things at the top, a proper structure to follow, and the basics are simple. The complex things are harder, but that's what editor tools or a CMS is for - handling the complex things so that you only need to write <a>, <img>, <li> and <p> tags.
