stereozoom2 is a pretty good and fast viewer of stereo pictures. It uses Allegro for UI and DevIL for loading images (therefore many image formats are supported). You may also consider using wxWidgets GUI.
stereozoom2 is fast, multiplatform and free, so if you need software like this, give it deffinitelly a try !
