User Interface Toolkit
User Interface Toolkit is a discontinued object-oriented layer atop the XView graphical toolkit. It was developed by Sun Microsystems employees Mark Soloway and Joe Warzecha as an internal tools project for Sun's Computer Integrated Manufacturing organization in 1990.
In 1991, Soloway got permission from Sun to contribute the UIT to the Massachusetts Institute of Technology X Window System distribution. Soloway continued development on the UIT, subsequently creating and releasing UITV2 in 1992. The source code is freely available.
