[comp.windows.ms.programmer] Creating a program for both mac and windows?

zee@fwi.uva.nl (Daniel M. van der Zee (I89)) (06/05/91)

hi all,

I've been asked by a small company to create a little computer program as an 
x-mas present for their business relations. The program should work under
macintosh and dos (windows 3.0) operating systems. To avoid making the same 
program twice on both machines, i'm looking for a programming environment that
can create executeables on both platforms.

The program is basically an address database with one extra 'notes` field. The
notes field must be able to contain up to 20K of text in different fonts and 
font sizes. It must also be printable (WYSIWYG). The program must also be able
to print a user selected group of addresses on labels.
The program must be very simple to use and have an on-line help function. The
user should be able to run the program without having to buy his own copy
of the programming environment. It is OK though if it requires a run-time 
version of the environment that can be distributed at no (or little)
charge.

I've looked at two alternatives so far: PLUS and OMNIS. I'm still waiting for
a demo version of PLUS to test some things out. OMNIS requires a run-time 
version that costs $300 a copy and has been dropped as a possibility.

Another alternative is creating two versions anyway. I'm a mac programmer
and it's no big deal to create a mac version, but how about windows. Does it
have a build in text editor that can handle different fonts and font-sizes?
How hard is programming windows? Is there an environment that can do the
things i want without too much trouble?

If anyone has experience with creating a program running under Mac and
Windows please tell me what program you used and what you experiences
were.

Thank You,
