Creation of generic Tree ?

edit

Hi, can i create a DAG- directed acyclic tree (not binary tree but generic)whose elements are instance of specific python class.

Pseudo code:

class x:
    def __init__(self,name):
          self.name=name

tree= Tree()
g1= tree.add_route(x("g1"))
g2=rt.add_node(x("g2"))
....

some thing like that ..
