I just need help about how to implement a graphical editor in java, just like the one in this image: http://www.sqlmanager.net/i/scr/orac...es_support.gif

I just want to put sometables (1,2 or more) like the "SH"."COSTS" and "PRODUCTS" of the image and move around the frame and trace lines between them (or more tables), I just need to edit inside the tables too... I just looking for ideas because I try to use frameworks as jgraph but they are to complex for my goal...

Any help will be appreciated.
Thanks.
