What do I need to write a Windows program with Ada?

["Vincent Smeets" <No@Spam.org>]

Hallo,

I know how to write a program with Ada and how to use X-Window (with Motif)
for Unix. Now I have a program (smal and non-commercial) that I want to port
from Unix to a Windows (98 or 2000) environment and give it a Windows-GUI.
It will use a menu, an explorer tree and some labels and buttons. The only
problem is that I have no idea about programming for the Windows
environment.

What do I need to be able to write a program in Ada for Windows?
-   Compiler
    I have GNAT 3.15p installed.

-   Description of a Windows API
    What APIs are there, what is the difference and where do I get a
description? Are there different levels like Xlib, Xt, Athena and Motif in
Unix?

-   Where do I get a binding for a windows API?
    GNAT comes with Win32Ada. Is that usable or are there other bindings
that are easyer to use? I have heard that MFC is object-oriented for C++. Is
there an object-oriented binding for Ada?

-   Do I need an C or C++ development environment for the Ada binding?
    Does the binding require some special libraries that are not generaly
available with Windows?

-   Books
    Is there a book you can recommend to read? I have started to read a book
about using MFC with C++ (from Microsoft Press). It gives me an idea about
programming for Windows, but I can't test anything because it requires
Visual C++ which I don't have.

-   Do I miss something?


Thanks for any suggestions,
Vincent
