Today, Web browsers provide a convenient access to the Internet while (1) increasing 
the number of useful desktop functions, and, (2) reducing the  platform dependence on 
the operating system of the host.  
This paper introduces a toolkit \texttt{WebWiseTclTk}
and demonstrates a range of its applications 
in support of a heterogeneous  computing environment where CAD tools,
data, and users are distributed across the continent. 
Specifically, we implemented {\em OmniDesk}, 
as a Tcl applet
that creates a user-configurable desktop within the  Web browser window.  
User can place any number of objects onto the OmniDesk, 
ranging from windows that display 
the contents of a directory or a file on a remote host, 
to {\em OmniFlow} applets that can execute
any sequence of 
user-defined, tool-specific, and data-dependent tasks.
Identical versions of 
OmniDesk and a variety of user-configurable  OmniFlow class libraries can be mirrored on several Web sites 
or can be installed locally for faster access and execution.
The \texttt{WebWiseTclTk} toolkit is an enhancement of the existing
feature set of Safe-Tcl and Safe-Tk, that does not compromise security. 
The toolkit re-defines the
functionality of the auto\_load mechanism in Tcl such that it works
for packages located anywhere on the World Wide Web. 
It also
re-introduces several commands not available in Safe-Tk
such as \texttt{toplevel}
and \texttt{menu} to provide a much richer feature set of Tk commands.
The toolkit is written entirely in Safe-Tcl/Tk and uses the
{\em home policy} for running applications as Tcl-plugins.
 
The toolkit supports 
(1) creation of new Web-based Tcl applications with greatly enhanced
functionality, and
(2) migration of existing Tcl applications to the Web by
merely writing an encapsulation script.
For example, only a simple encapsulation script is required
for Web-based execution of
the {\em Tk Widget Demonstrations}, distributed with the core Tcl/Tk.
