How do I store a status in MySQL easily?

I don't know PHP or SQL at all, only client-side scripting (HTML/JS). Basically, I would like to create a list with a few items which each can be added or removed by me. The functionality is so that if any of the items (.item) is clicked (well, if .item.mark gets clicked) a prompt shows "Would you like to mark this?" and if clicked yes, it gets stored in the SQL as 'marked', which results in a change of appearance. However if item.remove gets clicked, the mark gets removed.

"Bonus points": I want a prompt when the site is opened asking your name. The ID (#) gets hidden that equals the entered name

^{The thing that I would lik to create is an overview of each of my family members wishlist for Christmas. By marking each item it's shown that someone is buying that present.}
