Creating a web based point of sale system

I am considering of prototyping a web based point-of-sale system.
I don't have programming skills but I'm thinking of using this project in order to learn.

I would like to ask you the following two questions:

1. Do you think the above task is achievable within the period of 6 months (for building a rough prototype of the basic functions of a POS)?


2. If yes, which programming language would you recommend me and why? (I was thinking of Python)

Your advice is greatly appreciated!
