Why not?  Make sure that every class has a common superclass and a
static initializer that registers a constructor with a registry.
Then, when you want an instance of class X, call
theRegistry.newClass("X").  theRegistry looks up "X" and creates an
instance of X.  theRegistry is just a few lines of C++: it's a map
from string -> constructor.
