Training areas, to my knowledge, are AOI's (usually polygons) that refer
to the same attribute. If you need to make then, then you need to
digitize them manually. There no software in the world that could make
training areas for you! You train your computer to do the computation,
not the other way around!
 
But, if you mean classification, i don't think qgis can do that. You
need to use grass
