Write a program that creates a GUI window with following objects and their functionalities:

Two buttons left and right, with colors different from the window background.

Mouse click on the left button changes the background color of a button for a short period $($to

indicate mouse click on the button$)$ and increments a counter inside the button.

Mouse click on the right button changes the background color of a button for a short period $($to

indicate mouse click on the button$),$ closes the window, and terminates the program.

Layout and the content of the GUI window after $5$ clicks on the left button is shown in the diagram

below.

Implement function delay$($d$),$ which returns after a time delay specified by inter $d.$

Implement function is$\_$button$($click$,$ rect$),$ which returns True if point click is within rectangle rect and

returns False otherwise.

Initially put text $"0"$ into the left button, and text "Quit" into the right button. If the click was within left

button:

Turn the left button to another color, for example to grey: rect.setFill $(\text{'}$grey$\text{'})$

Use function delay$($d$)$ to wait for some time. Experiment with various time delays $d$ to find

the one, which gives a natural impression of pressing a button.

Turn the left button back to the original color.

Increment a counter and display its value on the text within the left button.

Slide $3,$ lecture $8\mathrm{.}5,$ explains how to use object Text to display a text on a button. Use method setText$(),$

slide $4,$ to change the value of the counter on the left button.

The algorithm for the main function looks like this:

Create a window $($win $=$ GraphWin $(...))$

Draw left button and text on the left button

Draw right button and text on the right button

while $($True$)$:

click $=$ win.getMouse $()$

if the right button clicked, break to terminate program

elif the left button clicked

change color of the left button

delay $(1000)$

return the button to original color

increment counter on the left button

close the window
