Web site automation?

I use Slackware 14.2 (64-bit) as my operating system, and I am considering creating my own website, and I want to know what software is available to help me do that. In particular, I want said software to be able to automatically generate any necessary code for it (which is not my area of expertise). I have checked out Bluefish (which seems to rely explicitly on writing code), so I guess you could say that I'm looking for a visually-based website builder. Any suggestions?

Thanks in advance.
