Feeding a News Ticker using an html form

I installed a news ticker plug-in on wordpress "ditty news ticker" and im trying to feed it from a form that im hoping to create on a seperate page.

I belive I would have do manipulate some of the plug in code in order to link them.

So the plug in only allows me to input text through the friendly UI dashboard.

My approach would be :

1. Create a form that receives input from user.
2. find the place in the code where text is inserted and insert something like : <?php echo $_POST["news"]; ?>

Im a beginner to html and php so please guide me if thats an incorrect approach.
