Start by first creating a world class for the calculator and the actor classes for the buttons and the display. You do not have to create a separate class for each button. All you need do is add an instance field in the class of the button that will be set to a distinguishing value (this could just be the String value that the button will have -- "1", "2", "+", "MR", "CE", etc.).

Please refer to the Java tutorials -- especially the trail on Learning the Java Language.

Greenfoot is just a set of tools and an API (the classes Greenfoot, GreenfootImage etc.) written in/for Java, so everything you write in Java will work in greenfoot. It's just that you have some extras with Greenfoot as opposed to clean Java.
