Its possible, I do it myself all the time.

	char *name_of_class = "test";
	VALUE klass = rb_const_get(rb_cObject, rb_intern(name_of_class));

	// (a) 
	//VALUE self = rb_class_new_instance(n, argv, klass);

	// (b)
	VALUE self = rb_funcall2(klass, rb_intern("new"), n, argv); 


As you can see there is two ways to instantiate (a) or (b).
