Well, to paint on the screen, you need to have some sort of graphic
interface on which to draw. So, you will have to deal with windows, events
and so on anyway, and Tkinter is probably about as simple as you can expect.
If nothing else, you should be able to copy and paste some demo code to
create a single window with a canvas on it, and use the canvas' graphic
primitives to doodle on it.

For example, this will create a window with a white background, and draws
100 random ovals on it:

from Tkinter import *
import random

h = 200
w = 300

class Application(Frame):
    def createWidgets(self):
        self.QUIT = Button(self)
        self.QUIT["text"] = "Quit"
        self.QUIT["fg"] = "red"
        self.QUIT["command"] = self.quit

        self.QUIT.pack({"side": "top"})

        self.doodle = Canvas(self, bg="#FFFFFF", height=h, width=w)
        self.doodle.pack({"side": "top"})

    def __init__(self,master=None):

    def do_something(self):
        foo = random.Random()
        for i in range(100):
            red = foo.randrange(0,255)
            green = foo.randrange(0,255)
            blue = foo.randrange(0,255)
            top = foo.randrange(0,h)
            bottom = foo.randrange(top,h)
            left = foo.randrange(0,w)
            right = foo.randrange(left,w)
                                    fill = '#%.2X%.2X%.2X' % (red,green,blue))
app = Application()
