I think you can split the drawing area into four with glViewport().. for example, if your drawing area is from 0/0 to 100/100

// first

glViewport(0,0,50,50);
gluPerspective(...);
gluLookAt(...);

// second

glViewport(50,0,100,50);
gluPerspective(...);
gluLookAt(...);

// third

glViewport(0,50,0,100);
gluPerspective(...);
gluLookAt(...);

// fourth

glViewport(50,50,100,100);
glOrtho(...);

or something like that http://www.opengl.org/discussion_boards/ubb/wink.gif
