Project Specification Your database of WIT persons is to be integrated into a cohesive program with a coherent user interface. When you start your program, your existing file of persons is loaded, and a dialog box is presented for the user to select one of the following operations: Add a person to the database; Display the whole database, one person at a time, with the ability to pay the person; Exit the program. When any of the operations is complete, this dialog will be displayed until the user closes the program. Adding a person When this operation is selected, another dialog box will open to select the person's role of Student, Faculty, or Staff. Make sure only ONE role can be selected. This dialog box can also be used to enter the name, W#, and address fields. Displaying the list of persons When this operation is selected, the first person in the list is selected, and the dialog box associated with that person is displayed with relevant data. On this dialog box, there be 3 buttons: Pay, Next, Done Pay button: runs any calculations and displays gross pay on a pop-up window; The Next button: dismisses the dialog for the present person and moves to the next person in the list. If no more entries exist, display the starting dialog; Done button: dismisses the person dialog box and displays the starting dialog Closing the program Closing the program causes the present database to be stored, and all windows dismissed
