[Tutor] OT python Licences

[Dave S]

This is a bit OT but here goes.

My work wants me to write a fairly large python script to analyze some
technical ASCII data files. Python and its libraries are GPL.

That being the case am I right in thinking that my script would also
have to be GPL and I would have to inform my employer as I hand it over ?

Secondly it would have to run in Windows, The results could pop up on a
DOS window. However I was looking at QT until I read the Windows
license. Are there any widget libraries that would allow me to program
for windows commercially without any license or fees ?

Thanks in advance
Dave
