Help me with a Java program that creates the following GUI

In this GUI, you will type an integer number in the middle text box and every time the Increment button is pressed, the number in the text box will increment by one and every time the Decrement button is pressed, the number in the text box will decrement by one. For example, the following images show that 125 in typed in the text box and after pressing the Decrement button, the value has decremented to 124.
