Creating a simple investment calculator) Write a program that
calculates the future value of an investment at a given interest rate
for the specified number of years. The formula for the calculation
is as follows:
futureValue = investmentAmount * (1 + monthlyInterestRate)years*12
Use text fields for interest rate, investment amount, and years.
Display the future amount in a text field when the user clicks the
Calculate button, shown below.
HINT: Note that the form asks the user to enter the Annual Interest
Rate. The monthly interest rate is 1/12 of that. Also, remember to
divide by 100, since it is a percentage.
