To write your own web pages (that are more than just you basic set of static pages held together with simple links)  you will need to learn:HTML:CSS:Javascript.Though there are tools to help you generate these you will need to understand these technologies intimately to use them well.To be able to generate the above you will need to learn:PHP (or one of the other scripting languages)Smarty (or the appropriate template engine for your language).SQL (mysql is a common implementation of the technology)Though you could learn Java instead of PHP (I personally (but others will disagree) think that PHP is better for web page generation). Java I would use to build more application/service like constructs were strong(static) typing is useful.
