How do you open the door of a 2003 Hyundai Accent with interior and exterior handles broken?

If both the interior and exterior handles of a 2003 Hyundai Accent are broken, you can try unlocking the door using the key in the driver's side lock, if accessible. If the lock itself is stuck or you can't open the door that way, you might need to use a slim jim or a similar tool to manipulate the lock mechanism from inside the door. If those options fail, consider removing the door panel from the inside to manually disengage the lock mechanism. If you're unable to do it yourself, seeking assistance from a professional locksmith would be advisable.
