Need to develop a cloud notepad. Where to start?

Hello, very soon I'll start a new project that will be very similar to Notepad cc (please google it, I can't put links here due to reddit anti-spam bot).

The problem is I have no idea where to start. Probably I'll not use a mysql database to store this info, and a login/password will not be required.

All I need is to enable a "save" button, where it will be generate a new URL, and the user will be able to open this URL on other computer or continue his work after a few minutes.

Any tips or ideas to what start searching and studying to develop this project?

Thanks!
