Ok, the patch is submitted

It uses Qt 4 libraries. It was developed on Linux with Qt 4.4.3, but in my 
experience, Qt applications usually work out of the box on any platform 
supported by Qt (X11, windows, MacOS X, framebuffer linux, windows CE). Only 
one pat of the terminal makes use of non-Qt functions: the Qt main loop is 
implemented inside a pthread, which is a problem because
1/ It doesn't work on non-UNIX platforms, but from what I understood from the 
wx terminal, Windows support would only imply putting #ifdef's around the 
pthread functions
2/ Qt does not officially support running the main event loop inside a thread; 
however, I did not experience any problem with this (except that Qt functions 
should be used with care in the gnuplot thread)
