Thank you so much for your input, muungwana, Neal. Truly appreciate it. Frankly, I am bent on QT4 as I have already QT4 Designer installed on my KDE system. However, as much as I know very little about its advantages, I don't know much of its disadvantages. Hence, soliciting your inputs. To many of you seasoned coders, this project may look plain and simple. It will be my first so you must pardon my ignorance.
@muungwana, what you pointed out makes good sense. When the time is right, I do want to let them know about this endeavor. I just feel it is the right thing to do. I really do not need their permission since the license state that I only need retain/reproduce their copyright but giving them notice might even make me another friend.

@Neal, I've played a bit with Zenity and it is easy enough to understand much of it. Thank you for pointing pinoc's addlocale and lomanager as examples.
As for what the python script actually does, I've been using it long enough to list and understand the options included, which are not really that hard to follow. And I do have an idea in my mind of what the window might look like. I'll post an image of this idea as soon as I get around to it.
Thank you to both of you.
