You need to choose a web framework. Django is more full featured out of the box than Flask or Bottle, which might be useful, but at the cost of more complexity. Go and read about them, try them out and make a decision.
Again, there's likely more stuff you need to learn about. As you begin building the thing, you'll find you encounter problems you don't know how to solve. At that point, ask.
Also, if this is for a business or something important (that is, rather than just some hobby project), have you put thought into how you're going to test it and where it's going to be hosted?
