How to create polygons with straight lines and right angles in QGIS?

In QGIS 1.8 is there a way to digitize buildings etc. with perfect 90-degree angles, Or, edit a polygon afterwards so that it has square sides? I have a buildings shapefile. I haven't been successful using the CAD Tools plugin. Thanks to everyone with advice.
