Having worked on an Apple cross-platform application that used the same APIs
that iTunes use...
...was a nightmare.
You'd think that it would be easy, but there are so many assumptions about
*how* the APIs work and work together to get your code running - and many of
those assumptions simply weren't true when running in a Windows environment. We
spent a significant amount of time re-writing various APIs used by the
application because the RedBox ones we had access to simply didn't work.
We won't go into the facts that every Windows font size is *exactly* 33% bigger
than they are on the Mac (Windows is 96 dpi, Mac is based on 72 dpi: 96/72 =
4/3). Or that a mouse on Windows was less precise but targets were smaller. Or
the myriad of other "issues" that make a Windows app just "feel different."
I've written apps in Qt, and it does make the cross-platform app development
process "easier" - but that's much more from a Windows-centric (or
Linux-centric) viewpoint. The same is true for WxWidgets. Qt also has a pretty
significant up-front cost in time and money (WxWidgets is open-source, but
still has the time investment).
