[Mingw-users] developing cross-platform GUIs

[Simson G. <si...@ac...>]

Hi. This is a question asking for opinions.

I need to develop multi-platform (Mac, Windows, Linux) and have been using mingw for my command-line C++ tools. I'm thinking of adding a GUI. my options:

1. Java GUI that calls the back-end via a TCP connection. 
2. Gtk+ compiled with mingw on windows.
3. Qt compiled with mingw on windows.

Does anybody on the list have real experience with #2 or #3? Does it work well? Are there pitfalls? Is it pretty transparent and cross-platform?

I did #3 a few years ago but haven't used Qt since the Nokia acquisition.

Thanks.
