java swing- create scrollable table

I need to display a table with persons names that have been entered.(using TabelModel and Tablecellrenderer)The table must include a column for person's first and last name, country, salary expectations. It must have column headers. If salary expected is above 100,000, must be displayed in red.
The table must have buttons to create, modify and delete entries. Also same functionalities must be possible thro a menu bar. When Sreate and Modify is selected, there should be a dialog box apperaring to input text. If entered item is already existing, should display appropriate message.  Table must be updated appropriately. Also an Exit button/menu should be there.

Thanks in advance.
