(Information from the Winteracter home page):  
Winteracter is a graphics and GUI toolset for Fortran 90 or later. It was originally developed and sold by Interactive Software Services Ltd. between 1997 and 2024, growing out of the earlier I.S.S. INTERACTER package (1989-2001). It comprises various visual development tools and a substantial subroutine library, which is compatible with many modern Fortran compilers.
