If solid wood, I don't think what you are proposing (gluing the ring to the top) will last very long before expansion / contraction of the top blows some of the end grain joints apart.
IMO, a circular apron should be either steam bent (which you have already decided against), laminated (which requires a form around which the strips are laminated) or built up using a technique I know of as "brick laying".
The apron it self should not be glued to the table unless the top is a made of something like MDF or particle board.
