Plugin Development End User Input

Hi,

I need to create a plugin where in the front end admin panel a user can enter a word inside of a single text box, they can then click “+” and it will add a second text box( if they wish ) which they can enter another word. This should be endless they can keep adding.

Then i need to add this as some sort of widget to display all the words. On a side note i’d want to be able to wrap the words in html so i can use css to style it.

Any ideas?

thanks.
