Please Help Me Code this in java

Write an application with three labeled text fields, one each for the initial amount of a savings account, the annual interest rate, and the number of years. Add a button Calculate and a read-only text area to display the balance of the savings account after the end of each year. Include another area with a bar chart that shows the balance after the end of each year.

All data entered by the user should be validated and there should be a quit or cancel button to end the program. Pressing the calculate button again will recalculate everything again.

It is the programmers responsibility to ensure that no matter what the user enters, the program does not crash.
