You can make a website in Photoshop, but I don't think you can make a really good website in (just) photoshop. Either you should learn the basics of html and css or you should pay one of the many many companies that makes your photoshop-image to a full-fledged html/css-site in 48 hours and pretty cheap.
I won't write that much about webdesign, but it seems everyone jumps on the chance to promote their
blog, so.. heh
