[orca-list] Possibly OT -- GUI development in Linux

[Stephen Clower <steve steve-audio net>]

Greetings,

I am interested in creating a cross-platform program that is accessible 
in Windows, Linux, and possibly other operating environments. The WX 
libraries appear to offer the cross-platform capability while utilizing 
controls native to each operating system. My questions to you more 
experienced GNOME developers are:

1.  Are the GTK components produced by WX Widgets accessible to 
assistive technologies such as Orca? I recall a discussion on this topic 
a couple of years back, and the prognosis for WX accessibility wasn't good.
2.  What approach did the orca developers take in creating the screen 
reader's UI? With the freely available Windows tools, I have made 
extensive use of a calculator to mathematically design screen layouts. 
Needless to say, this approach is tedious at best.
3.  Are Win32 programs compiled against the Wine libraries accessible to 
Orca?

My plan is to create the program in either C++ or Python, depending on 
which language will result in the least amount of changes across 
operating systems. Feel free to point out another language/GUI toolkit 
which I should investigate.

Many thanks in advance for any pointers. (no pun intended)

Regards,
Steve
