[tpoindex]

I did write a Tcl web system back in the 2000's that was close to the Tk programming model, although not quite a one-to-one. Here is an example of side by side programs for Tk and Aejaks: https://wiki.tcl-lang.org/page/%C3%86jaks+compares+to+Tcl%2F...

Some other screen shots: http://aejaks.sourceforge.net/Screen_Shots/index.html

This was made with the Java based Echo toolkit, and the Jtcl interpreter (Tcl implemented in Java.)
