I know quite a few programming languages, some better than others. I've written brief overviews, and in some cases tutorials for the following languages.

Programming Languages:

• BASIC
• C / C++
• COBOL
• DHTML
• HTML
• JavaScript
• Perl
• PHP
• Visual Basic
• Visual C++

I'm currently learning MySQL and a couple of other languages, so you can expect tutorials on those languages here fairly soon (say, within about a month).
