You might be surprised at how far you can go with this. Your situation
reminds me of the Oscar McMaster project, which is an open-source
medical system I am wrestling with. The target market is doctors,
who are not so tech-savvy and most of whom do not do any development.
But an ecosystem of service providers has sprung up around Oscar setup
and deployment. 

Having said that, doctors are accustomed to paying through the nose to
outfit their offices, and it sounds like your target market is not.

A cheap way around this might be to cheat. You could do your
development in MySQL and PHP, and then test the results both with a
standard Linux setup and using a WAMP stack like XAMPP. That would
increase the barrier to entry for Windows users a bit, but it would
probably be easier on you than trying to develop natively. 

I honestly can't see how this can be a desktop-only application
anyways, if you are thinking of tracking e-mails. There will have to
be a server sitting around someplace to handle e-mail interactions,
won't there?

I don't have personal experience with this, but I agree with John: the
database abstraction is probably cheap enough that you should just go
with it. If the abstraction layer is in place then people who use
Microsoft databases (SQL server, Oracle or whatever) can write and
maintain the plugins themselves.

Does a toolkit like wxWindows help with this? If I was in your shoes I
would be tempted to investigate things like wxPython, which promise
cross-platform compatibility and more rapid development than straight
C++. 

Java might also be an option here. Oscar McMaster is a Tomcat app (not
that I endorse this... getting this thing to run has been hideous).

I don't know about "easy to overcome", but I am pretty sure that other
projects have faced the same barriers and come out triumphant. But I
think that the decision of whether to go PHP/MySQL or try for a native
app is going to have far-reaching consequences one way or the other.
