OOP VGA++ (maclike) user-interface

[Douglas Allen Luce]

I'm developing a painting program (similar to a Macpaint clone) for
an IBM PC using Turbo C++.  Interesting parts of this project
are:

The actual image data will be in a 300 dpi format.

The display will be a 24-bit (512x512 or so) color system.

This paint program will have to do all sorts of things, but one of the
things that I'm hoping exists to ease the chore is a toolbox of routines
that implement dialogue boxes/choice panels/windows or the like.  

The mandatory qualifications is that they either work under VGA (or some
sort of 24-bit color system), or come with source (or drivers that can
be modified for 24-bit hardware), and that it implement the desired
functions.

Nice things for it to do would include being in c++ (and highly class
structured), and include mouse support.  And perhaps do some image
manipulations on the side.

If anyone's heard of such a package, please email me.

Thanks,
