SmartFTP Development

I am curious, as a developer, what language/framework was used to develop SmartFTP, and what GUI Toolkit was used? I'd appreciate an honest response, and the developers of SmartFTP can consider this a compliment.

Some hints were posted here https://www.smartftp.com/forums/viewtopic.php?t=5627. I guess some third-party libraries like BCGControlBar were used, too.

We use MFC with no 3rd party controls.

BTW: At https://www.smartftp.com/forums/viewtopic.php?t=7710 you state that SmartFTP 2.0 is a complete rewrite. I guess when rewriting an application nowadays, it doesn't make much sense to choose an old and proprietary GUI API like MFC anymore. Can we hope that you used something like wxWidgets (or Qt, FOX, whatever) and that maybe even SmartFTP ports for other plattforms than Windows will be available in the future?
