Here's the function I wrote, based on the previous answers here. It's a function instead of a class, which means you can use it in one line.

def get_text(parent, message, default=''):
    """
    Display a dialog with a text entry.
    Returns the text, or None if canceled.
    """
    d = gtk.MessageDialog(parent,
                          gtk.DIALOG_MODAL | gtk.DIALOG_DESTROY_WITH_PARENT,
                          gtk.MESSAGE_QUESTION,
                          gtk.BUTTONS_OK_CANCEL,
                          message)
    entry = gtk.Entry()
    entry.set_text(default)
    entry.show()
    d.vbox.pack_end(entry)
    entry.connect('activate', lambda _: d.response(gtk.RESPONSE_OK))
    d.set_default_response(gtk.RESPONSE_OK)

    r = d.run()
    text = entry.get_text().decode('utf8')
    d.destroy()
    if r == gtk.RESPONSE_OK:
        return text
    else:
        return None
