NetBeans and Cygwin? How to use X-term for "Run Project"?

I am writing a program that needs to be run from a Cygwin X-term due to the fltk graphics stuff. It builds and runs fine if I run it from a Cygwin X-term manually. But the NetBeans IDE "Run Project" button would only bring up a Windows command window, not even the Cygwin bash shell, let alone the X-term. I went to the project properties and the NetBeans options menus and couldn't find a place where I could add or specify the Cygwin X-term as the "Run Project" terminal. Any suggestions? Thanks! :)
