Yes, it is possible. You need to split your surface in several blocks, in an structure usually known as O-Grid <https://www.google.ca/search?q=o-grid&source=lnms&tbm=isch&sa=X&ved=0ahUKEwi-_tO9zPDMAhWJ7D4KHW83C6sQ_AUIBygB&biw=1024&bih=513>. That will help you control the density and orientation of the elements.
There are several .geo examples in the mailing list <http://onelab.info/pipermail/gmsh/>. Look for structured mesh in circles. Hope this helps.
