You can obviously start with a WYSIWYG editor such as Adobe Dreamweaver. That costs money and can actually do a lot right out of the box, but for starting out you can use something like Nvu.
I suggest learning the basics of HTML which quite honestly is not hard at ALL. especially since you know Lisp. Once you learn one language all the rest are easy to pick up. And also CSS, which is the way you style your page.
Any other questions you have when you get started, let me know.
