No-code or little-code website
What is a (free) technology which requires the least amount of code for creating a website with the following requirements:

- Sign-up/login
- Form for adding your personal info. which gets databased
- Each person can view and edit their own info
- Admin can view and edit any
- The form needs to be easily customizable and extensible (by the website's owner, not during run-time)

Is there a beginner tutorial for such a thing?

(For me, this question is about a friend who wants me to do this, but I want him to do it himself so I don't have to get roped into maintenance. I also want to keep it more general for the sake of Stack Overflow and future readers.)
