A short summary: - There are already Emacs implementations for all platforms supported by Qt4. - Qt is not a GNU project, some of the already supported toolkits are. - TrollTech's position on licensing is suspect. Doesn't bother me in theory, actually, as I believe that Qt should be considered part of the OS[1] where available, but I suspect many core developers would be wary of any dependency on a company with a history of non-free licensing. I think Qt is a non-starter, except as a bikeshed-painting exercise. Footnotes: [1] By analogy to Motif. Note that AFAIK the official position of GNU and the FSF is clear that toolkits like GTK+ and Qt are *not* part of any free OS. Therefore they must be distributed under GPL-compatible licenses to be linked to Emacs.
