Store the items in a dict as you create them:

self.itemDict = {}
itemTree1=QtGui.QTreeWidgetItem(treeWidget)
self.itemDict [itemTree1] = ??  # could be the associated widget that you want          
                                                       #  to connect to, or a                            
                                                       # string identifier
itemTree2=QtGui.QTreeWidgetItem(treeWidget)
self.itemDict [itemTree2] = ??

...

def function (self, item):
	widget = self.itemDict [item]
	...
