I'm am trying to make a three column layout for a website from an inkscape mockup that I made. The problem is that I am more of an artist that a programer, so I know only the basics. I will take any suggestions. Thanks!
Depending on your budget you could try http://www.psd2html.com/ or there are plenty of other options online.
There are probably automated solutions, but I've never found an automated tool that writes good, clean code.
With just a little bit of HTML and CSS knowledge, you can make some great layouts using the 960 Grid System. I've been using it for the last several projects I've worked on, and found it to be flexible enough for most needs.
Here's a tutorial on the topic. The float property is important to get a three column layout to work.

Some mockup tools (like Axura and ForeUI) can do this job, but you have to create the mockup with these tools before.
