This is not really a Tkinter issue, since you can fire up a
file browser window from a simple Python program. However, it
may introduce some special problems if you're doing it from
a GUI. Therefore, here is some sample code to illustrate how
to do this for Windows and Solaris platforms. You would have
to adjust for other platforms. Note that if you're doing this
just for Unix, that you don't need to thread: you can just
fire off the command in the background...

from Tkinter import *
from tkSimpleDialog import *
import sys, os, thread


class App:
    def __init__(self, master):
        self.master = master
        Label(master, text='Browsing:').pack(side=LEFT,
                                             padx=4, pady=15)
        self.entry  = StringVar()
        Entry(master, width=50, bg='gray', textvariable=self.entry,
              state=DISABLED).pack(side=LEFT, padx=15, pady=15)
        Button(master, text='Browse...',
               command=self.browse).pack(side=BOTTOM)

    def browse(self):
        path  = askstring("Browse", "Enter directory")
        self.entry.set(path)

        browser = Browse(folder=path)

class Browse:
    def __init__(self, folder='.'):
        if sys.platform == 'win32':
            cmd = 'Explorer %s' % folder
        else:
            cmd = 'dtfile -folder %s' % folder
        thread.start_new_thread(self.doIt, (cmd,))

    def doIt(self, where):
        os.system(where)


root = Tk()
display = App(root)
root.mainloop()

Hope this helps to get you started.

BTW: Chapter 18 of Python and Tkinter Programming covers
handling asynchronous events and things that block the
mainloop...
