Though there are many ways to format your gui code, the following seems to work well for me. It is not pretty, but the important thing is just how I laid it out.

Basically, I like making a subclass of frame for almost everything.

#!/usr/bin/env python

from Tkinter import *
import time
import tkMessageBox
import tkFileDialog
import tkSimpleDialog

class Demo(Frame):
  def __init__(self, parent=None):
    Frame.__init__(self, parent)
    self.pack()
    Label(self, text="Basic Demonstration").pack()

    errorbutton = Button(self, text="Error", command=self.showerror)
    errorbutton.bind('<Enter>', self.showerroronrc) #on hover
    errorbutton.pack(side=TOP, fill=BOTH)

    askbutton = Button(self, text="Ask", command=self.ask)
    askbutton.pack(side=TOP, fill=BOTH)

    openbutton = Button(self, text="Open", command=self.open)
    openbutton.pack(side=TOP, fill=BOTH)

    querybutton = Button(self, text="Input", command=self.query)
    querybutton.pack(side=TOP, fill=BOTH)

    Label(self, text="Name").pack(side=LEFT)

    checkoptions = ["check1", "check2", "check3"]
    for i in checkoptions:
      checkbox = Checkbutton(self, text=i, command=self.checkbox)
      checkbox.pack(side=TOP)

    #this is used in the showerror function
    self.ent = Entry(self)
    self.ent.pack(side=RIGHT, fill=X)

  def showerror(self):
    msg = "He's dead, " + self.ent.get()
    tkMessageBox.showerror('Error!', msg)

  def showerroronrc(self, event):
    print "stop hovering!"

  def ask(self):
    self.ynanswer = tkMessageBox.askquestion("question", "Do you like me?")
    if self.ynanswer == "no":
      print "fine, fuck you, buddy."
      Frame.quit(self)

  def open(self):
    file = tkFileDialog.askopenfilename()
    print file

  def query(self):
    myfloat = tkSimpleDialog.askfloat("Entry", "Enter a number")
    print myfloat 

  def checkbox(self):
    print "Don't check on me, bitch"

if __name__ == '__main__':
  root=Tk()
  Demo(root).pack()

  img = PhotoImage(file="./grass.gif")
  Button(root, image=img).pack(side=RIGHT)
  mainloop()
