+      wxWidgets gives you a single, easy-to-use API for writing GUI applications
+      on multiple platforms that still utilize the native platform's controls
+      and utilities. Link with the appropriate library for your platform and
+      compiler, and your application will adopt the look and feel appropriate to
+      that platform. On top of great GUI functionality, wxWidgets gives you:
+      online help, network programming, streams, clipboard and drag and drop,
+      multithreading, image loading and saving in a variety of popular formats,
+      database support, HTML viewing and printing, and much more.
