David,

You mentioned Native windows API for GUI development, and I appreciate the input. Have you looked at Qt? I heard that it is platform-independent. I heard that Qt uses the native API for GUI development on whatever platform it is running on. For native windows I have used a commercial product called Cobol SP2, from Flexus, it is multi-platform, but when running on unix it still requires a Windows ThinClient. For the HP3000 migration stuff I highly recommend SP2 for screen conversions, and the Eloquence DBMS for database conversion. But sill, I have no real Linux (or GNU/GPL) solution for GUI screens.

I've been using Linux for years, but only using it (network config, web/html , email, ftp, and stuff like that), no real programming. I've been writing Fortran, COBOL, and some C for decades in the mini-mainframe world, started with Fortran/66 in 1983, then ansi74 COBOL in 1986, very little C. OpenCobol is my path to multi platform programming. I really want to _thank everyone _evolved in developing OpenCobol. There are other areas I need to conquer in a multi-platform environment, GUI, DBMS, and System calls or intrinsics. However, right now I can't seem to compile anything worthwhile! When (not if) I get running with this, I'll be serious advocate for OpenCobol!

GTK is a UN*X toolkit, and a front end to the WinAPI.
It is rarely used on WinXP (even with Cygwin or MinGW).

A native WinAPI C application is relatively easy to write.
And since OC generates C code, it is easy to integrate.

Brian, maybe you could add an native WinAPI example to your FAQ, for
Cygwin (MinGW) users.

You can find a trivial example included in the TC source code [1]
(test.code/tgui02).

Hope this helps.
