One quick and dirty way is to open a GrafPort and look at the portRect.
This is a method I used in a couple of cdevs I wrote to center dialog
boxes on the screen.  Here's an excerpt...

----
Rect screenBounds;
GrafPort gp;

	/*
	** Get the size of the screen by opening a phony port
	** because we can't access screenBits.bounds.
	*/
	OpenPort(&gp);
	screenBounds = gp.portRect;
	ClosePort(&gp);
