I need a simple Jtable design quickly.

Hi I need a JTable with (-) at the end of each row and a (+) button at the end of last row for one of my projects. We are in a tight timeline. So I need someone who can start right away and complete it 3-4 hours. There should be 5 columns: Column 1 : ComboBox Column 2 : Text Column 3 : ComboBox Column 4 : ComboBox Column 5: Text apart from the Add Row (+) and Delete Row (-) button. Should be implemented in JTable. And should be able to sync the rows with my class which also has the same fields.I'll give the exact class ( has 5 fields) on finalisation. No universal bids. Please bid only if you have Java Swings experience. I need it fast .
