Need help creating and implementing a button class.

Hello, I am in the process of organizing, cleaning, and simplifying my code. I repeat myself a lot in my application, breaking one of the finest rules in programming, therefore I figured the best way to start cleaning up is with a button class. I have the buttons working outside of the class but got lost while trying to create and implement a new button class so I could use some help getting back on track. For now I am working towards simply drawing the buttons and changing the color when the mouse is over it.

    static String nomeLink;


 //size of buttons and the integers that load a view to the big square
 int toolSize = 20;

 //positions for each buttom
 int playX, playY;
 int pauseX, pauseY;
 int fastX, fastY;
 int reverseX, reverseY;
 int plusX, plusY;
 int minusX, minusY;
 String current = "";
 String view = "One";
 boolean constrain = false;


 //booleans to help decide which button the mouse is over
 boolean playOver = false;
 boolean pauseOver = false;
 boolean fastOver = false;
 boolean reverseOver = false;
 boolean plusOver = false;
 boolean minusOver = false;
 boolean play = true;
 int mode = 1;

 //naming our buttons
 PImage play1;
 PImage pause;
 PImage rewind;
 PImage fast;
 PImage plus;
 PImage minus;

   //Using to implement the class
   Button playButton, pauseButton, rewindButton, forwardButton, zoomIn, zoomOut;

   void setup() {
   size(1280, 360);
        background (51);
