Write a GUI application for the WebBuy Company that allows a user to compose the three parts of a complete email message: the “To:”, “Subject:” and “Message:” text. The “To:”, and “Subject:” text boxes should provide a single line for data entry. The “Message:” text area should allow multiple lines of input and be able to scroll if necessary to accommodate a long message. The user clicks a “Send Mail” button to send the email message. Your message content can be any of your choice, but should include at least two brief paragraphs of text. Provide an error checking to prevent sending an empty message email, or the one with the email address omitted.
