What problems are you trying to solve to write software for? I would suggest small programs, if desktop then console based until you learn how GUI programming works. Then you can move on to mobile and web that are different. What is your target operating system? Windows, Linux, Mac OSX? What is your target web browser? Internet Explorer, Firefox, Chrome, Safari, Opera, HTML5, HTML4/3.2? I would suggest learning simple HTML and CSS before learning Javascript. For mobile devices, well if you want an iPhone app you have to own a Macintosh and use XCode to submit apps to the app store. Android apps don't have limitations like that, and you can develop for them first.
