Cloning popups/panels

The piece of software I'm designing requires having multiple (ideally, an infinite number of) panels of the same kind open at the same time. 

Every clone should behave like it was an individual element (i. e. each of them can have it's own background colour and, whenever I input text, it will only appear in this particular instance of the panel) and I should be able to position them individually. 

Is this possible, somehow?
