When values between 0 and 1 are used, it refers to the fraction 
corresponding parent dimension. In your example, you are specify a
Window whose left edge begins 20% (0.2) of the screen width, and
the top edge is 20% of the screen height, and the width is 60% of 
the screen width and height is 60% of the screen height. So if your
screen is 800x600 pixels your specification is equivalent to ...

 create(Window, winName, 0, 160, -- 20% of 800
                            120, -- 20% of 600
                            480, -- 60% of 800
                            360, -- 60% of 600
                     0)

There are even more variations available for specifying relative
dimensions. Check out the documentation for the create() routine.
