Refering to this question, there are two different versions of the Autokey program: Autokey (Qt-based) and Autokey-GTK. What are the differences between a Qt-based program and the GTK one and are there any differences from the point of view of the user?

Note: this is useful to desktop users, not to developers using Qt.
sudo apt-get install qt4-qtconfig, then go to System / Preferences / Qt 4 settings and select GTK style in the first combobox:
Both packages provide the same application, but compiled with different dependencies (e.g. vim-gnome depends on libgnome2). Vim-gtk is important only to people who use Kubuntu (or some lightweight desktop environment) and don't want to install GNOME libraries. If you use the standard Ubuntu desktop, the dependencies are already present, and you can safely use vim-gnome. I agree that it could be confusing.

GTK and Qt are user interface toolkits and frameworks. GTK is the standard toolkit for GNOME/Ubuntu while Qt is used in KDE/Kubuntu. From the user's point of view I'd say it's just the looks that differ.
