How to create this Java program?

Can Anyone Show Me How To Create This Java Program?

• Write a Java program that validates an email address: 1. Using GUI to ask a user to enter a website address in the form of www.xxx.com, etc. 2. Validate that the website has www as the first 3 characters, followed by a dot (.), and then any valid name of the organization (characters/numbers), followed by a dot, and the end should be one of com, net, edu, gov, org, net. Using GUI to print out the valid one and the invalid one, saying why it is not valid. Then ask user to enter an Email address and do the same validation and printout. Please, I need all the help I can get. Thanks, ab28405
