You can detect if your program is running in a console with:

GetConsoleWindow() != NULL

However, this is probably not what you want - instead you want to check if
standard output is writable (you can probably create a GUI program and redirect
its output somewhere, and the program will work fine). I'm not sure how to do
that off the top of my head, though.
