For the error dialog you can easily use tkMessageBox:

just import tkMessageBox and then use this:

In [2]: tkMessageBox.showerror('Some Error', 'An Error occurred!')
Out[2]: 'ok'

If you're expecting a specific error you can use

try:
    #some statements
except SpecificError:
    #Handle the error

In this case (at least the block I looked at) it's just printing to
the command line. You can handle it using any one of the message boxes
or creating your own.

You could also try self.master.destroy()

when I tried:

from Tkinter import *
root = Tk()
root.quit()

in an ipython session. It didn't close my root window but the destroy
method did.
