PHP and javascript besides the ones you've mentioned.

jquery, css, html, php and sometimes java

to edit and create themes: html/css

jquery is not a language, it's a javascript library, and wordpress has absolutely nothing to do with java.

I currently know html, just properly learning css at the moment

jQuery and CSS are closely associated and jQuery is easier to learn compared to full javascript. Yes it is a javascript library but you actually don't need to know much javascript at all to use it.

Pretty much the only thing you really need is a basic to intermediate understanding of PHP and CSS. There are HUNDREDS of free templates you can learn from, most are built upon the same html layout.

Also go to wordpress.org and their development site Main Page « WordPress Codex there is where you learn all about how wordpress is put together and how plugins work. I personally learned most about wordpress by studying it's database and then backtracking into the code and the calls listed at Main Page « WordPress Codex you can use in themes.

Wordpress has it's own functions and classes that do all sorts of things, you do not need to code a lot of php yourself as they did it all for you. You will spend most of your time reading the codex site and studying templates and learning CSS.

If it's just simple edit, all you need is php and css

Another programming language so that you can edit your wordpress, PHP and Java is the best ones to learn.

Well, I guess your question is already answered above..

PHP will definitely be the most important one, followed by Java, SQL and CSS.

Before you start applying code as you're used to (outside WP plugins) - please be aware that WordPress has a lot of functions build in already (for example DB manipulations etc). Let WP work for you instead of building everything from scratch

You'll find all the existing functions at Function Reference « WordPress Codex

Hi,

Knowledge of PHP, HTML and CSS basically will help you.
But majorly before any customization, you would need to understand the coding structure of WP and its internal functions.

Yes, PHP ofcourse but learn PHP5 to work with wordpress. You should have grip on CSS as well to customize the templates to your needs.

You would need PHP, CSS and HTML. Get the hang of these ones and as for the rest, they will help you become a very good web developer aside wordpress.
