Create an HTML page with forms that allow you to add and remove email addresses

On a server, I have a file that has a list of email addresses.

I want a simple form that displays the the list like this:

-------------------------------------------
name@email.com [CHECKBOX]
name@email.com [CHECKBOX]
name@email.com [CHECKBOX]

[DELETE SELECTED]


Add new email: _________________ [ADD]
-------------------------------------------

The file that lists the emails is just plain text with each new email on a new line. I need a loop of some sort to read all the content from the text file and display it (with the checkboxes being part of the loop?). Then when they are removed, update the text file.

I'm not the most knowledgeable in this area so any help would be appreciated!
