It depends on what kind of site you want to create if you plan to create a forum you can use a software like vbulletin or phpbb. If you are planning to create a blog you can use blogger or wordpress. You can do all of these without learning any web scripting languages. you can also use sitebuilder of somesort to create a site.
Personally I mainly use xhtml ans css(both of which you can learn at
W3Schools Online Web Tutorials) to creat my sites.
