theres probably an easy way but you could use simple trig and a filled polygon.

x=sin(t)

y=cos(t)

should draw a portion then changing the sign +/- of x and y will get hte rest of a circle and just use these points for your filled polygon, ive never tried it in opengl but should easily work.

or

you could just use a quadratic disc, more setting up but easyer once set up, if yr not to sure on drawing circles with trig.
