*****JAVAFX*****

I have created a Form in JavaFX. This is a start. I now need help in adding fields for each course that the student is enrolled in (such as: SDEV200, SDEV264, CPIN239, CPIN269), but maybe the student only has 2 courses (SDEV264, SDEV200). I would like for them to be able to enter any number of classes necessary. Then the student can enter the course, and each course entered will have a field so that they can enter the number of hours they spent studying in this course. When finished I need a button that will give a dialog box for the total of number of hours they spent on each course with a grand total of hours spent studying.
