Add Form Elements On The Fly

I'm creating a news section for a CMS in PHP and mySQL in which I have a text field for the headline and an textarea for the article. Instead of making the user add each article one-at-a-time I would like to know if there's a way to dynamically create/remove these elements with a button?

for instance; at page load the form contains 1 article - it has 1 text field and 1 textarea. The user decides that he wants to add 2 more articles, so he clicks the "add" button twice. Now the form has 3 articles (3 text fields and 3 textareas), each with a unique id (art1_head,art1_txt, art2_head,art2_txt, art3_head,art3_txt).

Then, I also need to have a button or checkbox to remove each article.

Forgive my ignorance. I'm not a js guy, I work in PHP. Is this possible?
