FYI: According to IBM/OTI, Qt cannot be used for the original SWT 
because the free version of Qt for Linux is licensed unter the GPL and 
that license is incompatible to IBM's CPL. Therefore, they picked GTK+. 
  It is my understanding that Qt is also licensed unter the QPL and this 
licsense would probably compatible with the CPL but I'm not with IBM and 
IANAL.  However there's no technical reason preventing a Qt port and in 
fact, IBM has a Qt version of SWT which is used as part of their 
embeeded J9 VM for Linux.
