Do you like the functionality of KDE and the classic clean look of Gnome? I do. So I made some changes of the in QtCurve included preset 'KlearLooks'. The Differences are not too big but I like it that way a lot more and may be you too;-).
You might need to use the included color scheme or the color scheme 'GNOME 2.20' to make this theme look good.
By using these settings I use for GTK-apps the native ClearLooks theme.
