WHAT IS WXWINDOWS
* An open source C++ GUI framework to make cross-platform programming child's play. Well, almost.
* wxWindows is a 'framework' in the sense that it provides a lot of built-in functionality, which the application can use or replace as required, thus saving a great deal of coding effort.
* Link with the appropriate library for your platform (Windows/Unix/Mac, others coming shortly) and compiler (almost any popular C++ compiler), and your application will adopt the look and feel appropriate to that platform.
