my code:

#!/usr/bin/env python
import Tkinter as tk

class Application(tk.Frame):
    def __init__(self, master=None):
        tk.Frame.__init__(self, master)
        self.grid()
        self.createWidgets()

    def createWidgets(self):
        self.quitButton = tk.Button(self, text='Quit',
            command=self.quit)
        self.quitButton.grid()

app = Application()
app.master.title('Sample application')
app.mainloop()

error messages

Don't understand

orestgogosha, what version of python are you using?

"Tkinter" is from post python 3x

To have the code work simply change the "Tkinter" in your import line to "tkinter" (proper for python versions 3x).
Keep in mind that when you run this code it will not close correctly when you click the Exit button because there is no definition statement in the code. I'll let you code that in for learning purposes.

#!/usr/bin/env python

#Changed Tkinter to tkinter for python versions 3x.
import tkinter as tk

class Application(tk.Frame):
    def __init__(self, master=None):
        tk.Frame.__init__(self, master)
        self.grid()
        self.createWidgets()

    def createWidgets(self):
        self.quitButton = tk.Button(self, text='Quit',
            command=self.quit)
        self.quitButton.grid()
