You can't be a web developer unless you can code. I think a good exercise would be copying a website. When I say copy I mean the whole thing front end and back end. Start with something easy like twitter. The whole front end is pretty much done for you. This is not super simple but I don't think you can become a developer in 12 months with no code experience anyway.
