Making Kde4/Qt4 apps look like Gnome/Gtk

1) Get QGtkStyle using svn - http://labs.trolltech.com/page/Projects/Styles/GtkStyle
Or
Download a .deb from here

2) Get qt4-qtconfig

sudo apt-get install qt4-qtconfig


3) Run qtconfig-qt4 (Using alt+f2). Select the GUI Style as GTK and File>Save.

4) Incase this does not work, install these packages:

sudo apt-get install kdebase-workspace systemsettings

Then run systemsettings. Go the Appearance section, and change the Widget style to GTK.
