Well, I admit I know even less about Tkinter than most other aspects of
Python,
but I _think_ you just need to inherit Dialog from Toplevel instead of
Frame:

from Tkinter import *

class Dialog(Toplevel):
   def __init__(self,parent):
     Toplevel.__init__(self, parent)
     l = Label(self,text='initial text')
     l.pack(side=TOP)
     b = Button(self,text='close me',command=self.destroy)
     b.pack()

class App(Frame):
    def __init__(self,parent):
        Frame.__init__(self,parent)
        self.pack()
        w = Label(self, text="Hello, world!")
        w.pack()
        b = Button(self,text='open a dialog',command=self.makeDialog)
        b.pack()

    def makeDialog(self):
        Dialog(self)

root = Tk()

theApp = App(root)
theApp.mainloop()

HTH,
