Do you want to program stuff or do you want to write websites? The two tasks are fundamentally different from each other, and different languages are used for either.
For building websites, you'd start out with learning HTML and CSS.
For writing programs, I'd suggest either C++ or Java. (some people suggest Basic, but I personally disagree cause I don't like it :O)
After that, it depends. If you want to go down the path of a web designer, you'd probably want to learn javascript, PHP, perl, SQL (MySQL is a DBMS, SQL is the language - people keep getting this down wrong) and stuff like that, as a programmer you'd want to extend your knowledge on how computers work in general, how programming languages work, and how to use various specific programming libraries. So, it depends.
Also... Seriously, I want you to remember this: HTML is NOT a programming language. Programming languages are used to write programs. HTML files are no programs, they are files consisting of information how the website should look like. HTML is a MARKUP LANGUAGE. That's why it's called HYPER TEXT MARKUP LANGUAGE, not hyper text programming language.
And don't use WYSIWYG editors. Sure they are easy to use, but you'll learn NOTHING from using them.
