Newbie Question on a Code - I don't know if this is Java

I’m an absolute beginner so please forgive me if my post is out of place or has no business here. If my question is out of place here, then if you could tell me where I can go I would really appreciate it.
There’s a web site called How to Keep an Idiot Busy (How to keep an idiot busy )and it’s a silly, time wasting, no-win game of futility where the goal is to try a press a submit button that keeps moving away from your mouse just as you get near it and are about to press it. I would like to put a variation of that in a website as a joke and I was wondering if anyone here can show me or tell me how I can do it. Again, I am a newbie, so I don’t know if this Java or JavaScript. Is it a code that can be easily pasted in a Dreamweaver file? I appreciate any help you can give me on this. Thanks.

I haven't looked at the site, but you could certainly do this in a Java Applet. You could probably also do it with javascript, but that is not the same as Java. Chances are you're looking for a javascript forum.

Or you could just take a look at the site's source and see what they're using.

I don't think there's a red enough color that could illustrate my embarrassment. Thanks for taking the time and giving your fingertips a gentle massage by tapping some keys on your keyboard, but I don't know what an applet is or where I can get one to do something similar to that site. It seems your gut feeling tells you it might be JavaScript, so perhaps I should explore that route. I'll go take a look in that direction. Thanks KevinWorkman.

It is an applet (not javascript). Should you wish to step into the realm of java programming, here are some links to Oracle's tutorial pages to help you out

thanks copeg. I bookmarked the links you suggested and I'll wade in carefully.
