I would start by looking into HTML and CSS. The are just the basic markup languages for the web. Once you have conquered those, I would move on to a server side scripting language such as PHP or ASP. As a programmer you will pick up on the logic naturally but you will need to learn the syntax. You might find it worth your while to learn MySQL, Postgresql or MsSQL. These are web databases and will allow you to create really cool web applications.
You will also need to learn how to use JavaScript. This has become a key scripting language in web based applications and comes in VERY handy.
- So just to recap -
You need to learn:
HTML
CSS
JavaScript
PHP or ASP
JavaScript
MySQL, Postgresql or MsSQL
Here is a really good website for starting out: http://w3schools.com/
