I'm assuming that self.GetItemText() in OnCelChanged() returns a URL? 
In that case you can simply pass that to HtmlWindow.LoadPage().  You'll
need to pass a reference to your HtmlWindow instance to your channelTree
instance so that it can call LoadPage()

class channelTree(wxTreeCtrl):
   def __init__(self,parent,id, htmlWindow):
       wxTreeCtrl.__init__(self,parent,id)
       self.root = self.AddRoot("Sites")
       for i in range(len(names)):
           self.AppendItem(self.root,names[i])
       EVT_TREE_SEL_CHANGED(self,105,self.OnCelChanged)
       self.htmlWindow = htmlWindow

   def OnCelChanged(self,event):
       item = event.GetItem()
       self.htmlWindow.LoadPage(self.GetItemText(item))
