PERL and C++ are always good to learn. i started out learning PERL from the PERL quest guide in the quest forum and then moved on to more advanced stuff from there. now im learning C++, however i bought a book to teach me that.
i would suggest tho learning less complicated languages first. like HTML.
heres the order i learned things in:
1. HTML
2. PHP (just the basics)
3. Javascript (basics for the most part)
4. PERL
5. C++ (still learning)
i didnt really get to big into PHP and Javascript but it would probably be easier for you to learn PHP before starting any other Object Oriented language like PERL or C++. I never really learned SQL. I'll probably learn that after i get fairly good with C++. If you want to learn C++ the book "C++ For Dummies" is pretty good. thats the one im using and it doesnt require too much prior knowledge to learn (like a lot of other books that require you to know C before learning C++)..
but ya, if you don't know any other languages I would suggest starting off at lower level languages like HTML. HTML is easy as hell
