Developing HTML/CGI-Apps is exhausting
Developing CGI apps and/or HTML-Dialogs is exhausting and time-consuming, even with tcl. Generating HTML syntax is complex even with the help of html, ncgi and other packages. Maintaining session states makes things even more complicated.
What came in my mind is the idea to use tk-Syntax to generate HTML-Dialogs, e.g. entry generates an <input>-Tag and so on. It's clear that the capabilities of a native GUI and HTML-dialogs aren't congruent.
