How would this be different from:
 
b1 = ButtonDescription():
b1.size = (40, 40)
b1.text = "b1"

or from this:

def instance(klass, **kw):
    inst = klass()
    for k in kw:
# could add a check for __getattr__ here
        inst.__dict__[k] = kw[k]
    return inst

b1 = instance(ButtonDescription, 
         size = (40,40), 
         text = "b1")
