Since the last correspondence did not lead to any result, I decided to request solution planning another similar scenario.
In echo2 framework which acts closely like a swing project, I need to develop a graphical diagram based on my database records which every record represents a button-like entity to open the detail of that specific record when the user clicks on it.

Now, the questions are:
1- any suggestion how to develop this diagram with graphical entity relations and among them?
2- if I decided to resolve the problem using swing-like-buttons, as the records count do vary how do you suggest to declare button variables?
