I'm completely stuck on how to organize the layout of this GUI assignment (see:attached picture) I've got the create panel part done, but I can't get anything to work properly for this panel. I've done the code up to the updatePanel method and it compiles but nothing displays. I've tried a few other ways that will display but nowhere close to where they're supposed to be. Any pointers in the right direction would be greatly appreciated.
