tkinter is likely the easiest solution. Here's a quick hack, assuming
you want a program with a single window, rather than dialog you can
pop up. This has no cancel button since you didn't specify you wanted
one. It just pops up a window, and when you press ok, <return> or
dismiss via the window manager, the edited value will be printed to
stdout. It's not a perfect solution but it gives you a feel for how
easy it is to do with tkinter.
import Tkinter as tk
class App(tk.Tk):
def __init__(self, s):
tk.Tk.__init__(self)
self.wm_title("Edit the string")
# the main layout is composed of four areas:
# 1) the label / instructions
# 2) the original value
# 3) the edit field
# 4) a row of buttons
label = tk.Label(self, text="Please confirm or edit the
following string:")
oframe = tk.LabelFrame(text="Original:")
eframe = tk.LabelFrame(text="Edited:")
buttons = tk.Frame(self)
orig = tk.Entry(self, width=40)
edit = tk.Entry(self, width=40)
edit.insert(0, s)
orig.insert(0, s)
orig.config(state="disabled")
ok = tk.Button(self, text="Ok", command=self.ok,
default="active")
# this does all the layout
label.pack(side="top", fill="both", expand=True)
oframe.pack(side="top", fill="both", expand=True, padx=4)
eframe.pack(side="top", fill="both", expand=True, padx=4,
pady=(4,0))
orig.pack(in_=oframe, side="top", fill="x", padx=4, pady=4)
edit.pack(in_=eframe, side="top", fill="x", padx=4, pady=4)
buttons.pack(side="bottom", fill="x", pady=4)

edit.select_range(0, "end")
edit.bind("<Return>", lambda event: self.ok)
self.wm_protocol("WM_DELETE_WINDOW", self.ok)
edit.focus()
# keep a reference so self.ok can access it
self.edit = edit

print value
self.destroy()
