Develop a GUI based Java application that interacts with Excel spreadsheets

The application requires “JExcelAPI?? ([login to view URL]). I need to develop a GUI based Java application that will interact with Excel spreadsheets and generate an enrollment analysis report for one or more academic departments of a college.? I have a data file, a document with specifics about what the application should be able to do, and a sample output if you decide that you can do this. I would like the program back by July 31, or sooner if possible. I'm looking for? something I can understand and that is easy to modify. Nothing fancy at all. If you can do something in 1 step, break it down into 3 - real beginning Java methods here. I need new, fresh code not taken from the Internet. All files will be sent if bid is accepted.
