How would I create a basketball shot meter like this?

https://gyazo.com/f575910990728fd42675f3a13ab8d844 How would I start? How would I begin to script this?

I was thinking getting a basketball tool and when they have it equipped than use UIS to get input for "e" but when they hold it down. But how would I timed it to hit the middle white line in the shot meter. How would I also make the gui go up with holding the button?
