I was thinking primarily about python/qt. Any advices?
Is the constraint about working without a network connection or an internet connection? Are the terminals connected to an internal network to access files, communicate?
>We need to create/revamp some small internal tools used by our engineers.
What's the goal of that revamping? What is wrong with the current tools?
How frequently will you be updating the tools, and how do you see rolling out new versions? What has been the workflow like for fixing bugs or improving the tools so far?
WPF seems like a nice idea, but it's tricky to get into, has limited penetration/support, and it's never been very clear whether Microsoft have abandoned it or not (including to Microsoft, I sometimes suspect).
If it's a basic app, basic WinForms should do just fine.
You don't need access to network, have full access to file system, sqlite, etc and engineers for Javascript/HTML are dime a dozen so may not need to learn a new language. Also in case you need to switch to another OS it's cross platform by virtue and can be easily ported to web easily should the need arise one day.
