GUI COMMISSION CALCULATOR CODE

Write a Javaâ„¢ GUI application using NetBeansâ„¢ Integrated Development Environment (IDE) that calculates the total annual compensation of a salesperson.

Consider the following factors:

• The calculator should allow user to enter the amount of sales
• The calculator should allow user to select the level of commission rate from a list of pre-defined commission rate. The three choices in the list are:

• Entry member = 3.5%
• Journeyman member = 6.75%
• Senior member = 11.25%

• The calculator should display the amount of commission in dollar, based on the amount of sales entered and the commission rate selected.
• The Java^â„¢ application should meet these technical requirements:
  • The application should have at least one class, in addition to the application’s controlling class (a controlling class is where the main function resides).
  • There should be proper documentation in the source code.
