You act as if Qt isn't already a successful cross-platform toolkit. Qt has been successfully used for years to make native-looking apps for OSX, Windows, and Linux from the same codebase.

How are you saying Qt has not succeeded as a cross-platform GUI system, or that it produces non-native apps on the platforms it has historically supported?

And yes, my customers -do- want my software to run on Android and iOS just like it runs on Windows, Linux, and OSX - and they don't particularly care in what toolkit it is written. I do, however, care about having to re-write the same code in three different languages.
