Proxy Tk: A Java Applet User Interface Toolkit for Tcl

Proxy Tk allows a Tcl program to provide a highly interactive web-browser user interface, without requiring the end user to download additional software. It uses a thin client design, where a server-side Tcl application communicates with a very small generic Java applet running in the browser, sending it commands to create and modify widgets, and receiving events from the user. A Tk-like layer encapsulates the communication protocols to provide a familiar programming paradigm, and allow easy porting of existing code.
