I believe what you want is created using AJAX ([SIZE=-1]Asynchronous JavaScript And XML). As in your enter something in the page, hit a button and it just appears there without the page refreshing - that's done using AJAX.
If you want some tutorials on the subject then
Google is your friend.
This isn't for anyone new to programming though. You'll need some experience with JavaScript, XML and some knowledge of how web pages/servers work to understand it fully.
