I am be no means any expert on this, but I feel I still can add a couple 
of comments. I looked into the accessibility functions on MS Windows 
some years ago. I was interested in running programs automatically (for 
testing purposes). It turned out that this was technically very 
difficult (but possible) with old windows controls, but that the newer 
controls had support for this - in exactly the form of accessibility 

I believe Microsoft has put some effort in making all newer controls 
working with their accessibility framework (MSAA). So making basic 
accessibility work in MS Windows applications is possible by just using 
standard MS Windows controls. The keyboard support though, has to be 
made specific for every application, but the basic support for doing 
this is their and it is not difficult.

To my previous note about using wxWidgets I should add that it looks 
like not all wxWidget controls have accessibility support yet, but it is 
currently beeing worked on, see

Kind regards,
