I love computers. In fourth grade, I started to type up all of my homework since my handwriting is basically illegible. I got straight C's in penmanship. I've been programming since I was in high school, spending my algebra class typing away on my TI-82. I started programming for real in Turbo Pascal on 386 machines. These were so old that they had floppy disks that were actually floppy, and had ``turbo'' buttons on the side that actually made them run faster. These days, I have two Masters degrees in computer science, and I'm working on my doctorate. I love computers.
Alright, enough reminiscing from me. If you want to learn a beautiful programming language, and learn how to develop web pages, I very highly recommend Ruby on Rails. Ruby on Rails is a framework that uses the Ruby language to create web pages. It ties together HTML for the front end and SQL for the backend, in a unified environment. Ruby on Rails is used by a number of popular websites, including Twitter and Groupon. Best of all, Ruby on Rails has a wealth of online resources available, provided by a devoted community. Google will answer most of your questions.
For myself, I use Ruby (the programming language) and Ruby on Rails (the web development framework) all the time. Ruby is a flexible, powerful scripting language. It is a joy to program in, and while I've been using it as my main language for years (grad school generally lets you use whatever language you like), I'm still discovering more about it. Ruby on Rails has allowed me to build many, many websites for my research over the past few years; I even wrote richshay.com in Rails 3.1 as a learning exercise.
So, that is my suggestion to you. If you'd like to start learning Ruby, and Ruby on Rails, all of the tools that you'll need are entirely free. OSX comes with Ruby and Rails installed already, and you can download them for free in other operating systems. I highly recommend Michael Hartl's excellent Ruby on Rails tutorial for learning about Ruby on Rails (
http://ruby.railstutorial.org/ruby-on-rails-tutorial-book).
Best of luck with this.
