Question

GUI for Math Operations ( In JAVA using WidgetView , in simple beginner java) A couple people posted this same question and I also posted this earlier today but got an answer that did not show the whole code and did not use WidgetView, could someone please read carefully and show me the correct code USING WIDGETVIEW. thanks in advance.

Write a program that asks the user for 2 integer numbers and displays those numbers added, subtracted, multiplied, divided and modulo.

Use a WidgetView object.

In your GUI, display a label containing instructions to the user such as "Enter two ints and I'll perform math operations on them."

Create two text fields for the user to enter the numbers.

Use a button for the user to indicate that he has entered the numbers.

When the user clicks the button, display labels showing the results of each operation with an indication of the operation performed, such as "adding 7 and 8 is 15."
