[news.eclipse.newcomer] Adding own application as button to workbench ?

["klm" <asd@xxxxxxx>]

I have written a simple application in java. Now I would like to install 
this application in the eclipse framework and make it possible to run it 
pressing a button in the workbench. I assume this is what writing plugins 
for eclipse is all about but how do I get started in the right corner?
