Design your GUI once. Generate both native Motif and native MS Windows GUIs at once. XFaceMaker/Win generates code that uses the native objects of your target platform. There is no emulation" which sacrifices native features and which lock you into proprietary code.
And, unlike layered toolkit API's, XFaceMaker/Win generates standard MFC code for Visual C++. Now you can deploy polished, native GUIs with consistent appearance and behavior between UNIX and Windows. And UNIX server-based applications with Window clients.
Because the XFaceMaker family is fully extensible and customizable, you can easily integrate third party widgets/controls or build your own customized classes that can be used on multiple toolkits.
