Simple GUI for my personal Assurances

Hello everybody, I'll need a simple program (with gui) where I can enter all my assurance informations. The program should be split in to sides. On the right should be the assurance (i.e. car) and on the right should be the information about it. The data should be stored in an xml file (no sql db) and it should be documented how I could add new categories to the right menu in the source by myself ## Deliverables Attached you'll find some simple screens, how the program should look like/work. Please contact me if you have any questions
