class FontController:
    def __init__(self, model):
        pass

class Model:
    pass

def getClass(classname, modulename="__main__"):
    return getattr(__import__(modulename, globals(), locals(), [classname]),
classname)

model = getClass("Model")()
print getClass("FontController")(model)

Should be fairly self-explanatory :-)
