Is there a basic sound tool, in the form of a C-function or Objective-C method, that causes sound to be emitted from the Mac loudspeaker (for example, for definiteness, a 440 Hz sine wave, for 1 sec)?

  NSBeep()? ;-)

Seriously, though, you might want to check out CoreAudio for such specific frequency generation.

As to hitting a specific audio output device, it's possible, but you should defer to the user's preference, since the audio device you selected for output may not even be powered on / plugged in / whatever.

Also, assuming only the default audio output, if they've got something plugged into the headphone jack, you won't hit the internal speaker. I'm not sure it's possible to bypass this particular roadblock with software.
