There are no simple way to make mesh from scratch :). Moray 
is not a mesh modeller, this is more a solid modeller. To do 
mesh you must use another soft like Spatch 
(http://www.cableone.net/alyson/spatch.html). With this soft, you
can export into Bicubic patch (.Pov), Bicubic patch (.mdl,
go to the plugin page of Moray and load the spatch plugin which 
allow you to export into Moray) or Mesh (.dxf). But you can use 
other more commercial soft to do mesh.
If you export in dxf, you convert it into inc/udo with 3dwin and
convert it into mesh2 with Mesh Compressor. This is not simple
but this is the prize to pay for free (or low cost) software :).
