WordPress Theme Development Tutorials and Resources
WordPress is the most popular content management system (CMS) in the world, powering over 25% of the public web. It is popular in part because it is free, easy to use, and easy to host. It is also relatively easy to develop for. Many web designers and developers have gotten their start by working on WordPress — and many have made a lucrative career out of it.
The structure of WordPress separates out content from design and functionality. Content is stored in a database, customized features are added with plugin-ins, and the design of a site is controlled by a theme.
If you want to design themes for WordPress, it helps to know some PHP, but the most important thing is HTML and CSS. In addition to basic coding skills, there are a number of WordPress-specific thing you’ll need to learn in order to become a successful theme developer.

If you are only going to buy one book on WordPress, this is the one to get.

If you just open up the default theme and start messing with the code, you’ll probably learn a lot — but you won’t end up with a stable and maintainable theme that you can use on a public site or release in the Theme Directory.
However, if you follow the advice in these tutorials and use the tools listed above, you’ll be able to create beautiful new themes and stay sane while doing it.
