Panel Plus II is a screen painter and C UI library with support for OS/2 and VAX VMS and the possibility of a DLL version on OS/2 and DOS which opened up support for FORTRAN as well as C on those two operating systems. The company shortly after that added support for UNIX, Xenix and QNX.

By the time version 2.1 hit the market in 1991 the library not only supported the usual multiple windows and menu options but had added features such as field editing capabilities that include automatic conversion of currency and date formats to different national standards and full word-wrap text editing.

The system is still being sold in 2016, albeit without any form of support but with full source code.
