Lots of things to consider.
Plywood vs hardwood?
Oval vs rectangle? Or something more unique like what
@Shaggy posted with the fancy corners?
Skirting?
1 piece? Multiple pieces?
Size?
If you can get away with it, the easiest thing to do is grab a sheet of 4x8 plywood, cut it down to size (size of your poker table + ~3" in both directions if you plan to use 3/4" plywood for skirt, and a slight recess from the edge of the table to the skirting). Add veneer edge banding to the edges. Cut some skirting pieces and screw them in from underneath to the table. Add some stain and polyurethane and you're done.
All other iterations get much more complicated. If you're going with an oval shape, then kerf cutting the skirt going around the ends is your best bet. Steam bending is mucho hard, as well as veneering 1/8"-1/4" strips.
