Key mapper for SH3

[Thoth_already_in_use]

Greetengs Capitains!

I'm unfortunate user of AZERTY keyboard, so I searched for a key manager for SH3. I found one, which comes with LSH 2015, but it was barely usable. Thus I started to create my own (c.f. screens). In the current state it reads the Commands_en.cfg, and put key-list on screen. Actually it detects the conflicts (same key for different actions and overlapping contexts).

I write in C++, with NCurses library. I would like to write it for Windows, but I never coded for it, and I have no idea how to make an Windows GUI. If there are an expert who could help me to move on Windows, I'll be grateful.

1) Is it of any use? Probably there are already an user-frendly key mapper that I'm not aware of.
2) That exactly context means, and how it defines the keys? For example the space-bar used for 'select target' in binoculars and 'fire' in gun, however both actions have same context.
