Tk is a companion program to Tcl for creating graphical user interfaces. Together with Tcl, Tk is a rapid program development tool from Scriptics. Both can be ordered from the Scriptics Web site.

Tk provides a collection of standard buttons, menus, listboxes, and scrollbars and two special features, the text widget and the canvas widget, that the Tcl programmer can use to speed up program development.
