You can set DEPENDS in the qt4-x11-free bbappend just as with any other 
variable. In this instance you could use the _remove operator e.g.

DEPENDS_remove = "gstreamer gst-plugins-base"

(This will only work here having additionally set QT_PHONON = "-no-phonon" to 
disable the underlying depenendency, of course.)

Cheers,
Paul
