In openGL you are always busy with rendering the scene so when the user undoes then you remove that object from your list of the objects that should be rendered. It doesn't seem very complicated.

What do you mean by "make a button"? Buttons are already available, you don't need to "make" then unless you need some non-standard rendering/behavior.

Have a look at the Command design pattern (you may start at related Wikipedia page[^]): you may gain some insight.
