You can do this, but you'll need to use the Win32 API to attach to a
console (command shell) and be able to read and write to its STDIN and
STDOUT.  See the links below:

<http://www.dreamincode.net/code/snippet921.htm>
<http://www.halcyon.com/~ast/dload/guicon.htm>
<http://msdn.microsoft.com/en-us/library/ms681944%28VS.85%29.aspx>

The first two are links to examples, and the last is to the MSDN
documentation.  It's been a number of years since I did this, but it's
the technique that Visual Studio uses to run the command-line
compilers and pipe their output back into the IDE.
