GNUstep Windows Developer 1.4

GNUstep is a cross-platform, object-oriented framework for desktop application development.
GNUstep features two great graphical applications which help you manage and create new projects, design and edit graphical user interfaces, & compile and debug your programs. The core libraries contain classes for developing a complete graphical application for almost any purpose.

Based on the OpenStep specification and now compatible with Apple's Cocoa framework, GNUstep enables developers to rapidly build sophisticated software by employing a large library of reusable software components.
