Mission Impossible #1: qt without gtk

[Eugene Pivnev]

As I'm trying to create gtk-/gnome-/kde*-free environment (QtDesktop) - 
I tested - what about Fedora without them?
So:
1. yum remove gtk3:
...
* gvfs
* qt-mobility
* qtwebkit
* ffmpeg
* ffmpeg-libs
* mplayer
* phonon
* smplayer
2. yum remove gtk2:
<all above>+
* ImageMagic
3. rpm -qa | grep gnome | xargs sudo yum remove
* git (???)
* gvfs

Question is: why?
