Java SE (Java Platform, Standard Edition)

Hi,

I'm trying to make for my application sort of like a panel where the user will have in the background a JPG image that will be a map and on top of that I need to have smaller images or icons that will be nodes of a network and those nodes will have to attributes that will determine the position in the screen to fit the map underneath.

Also every node will have to be able to be clicked to open another window that will contain data from that node.

I'm new to Java and I don't know which is the best way to do that in Java. Can someone point me to the right direction?

I thought of using Icons or maybe buttons with the node image on top. But I'm not sure if that is the best approach.

Thank you.
