I suggest you don't code at all. Do a very detailed mind map of the project. It will include, the users you are targeting, what's the goal -- why are they better off with your project, how will you get customers, and there is so much before you start to code.

As a learning project, copy a successful project and mind map it, program it and find customers. You will learn so much that you can apply to whatever project you come up with. You'll get frustrated because you will need to go out and learn a lot but power thru it. You'll be better off for the hard work. Good luck!
