You probably will never find a "pure" version. Tk is an extension of =
Tcl, specifically designed to interface with GUIs. While Tcl and Tk =
have separate names, like EX and EXW, they are basically inseparable. I =
don't know how it works in MS land, but in Linux it requires a special =
shell to use. That might make implementation a bit difficult. C and =
ASM code can be accessed on the system level, so using DLL's or inline =
ASM code at runtime is no problem. If anyone knows of a compilable or =
"straight" version of Tcl/Tk, it could be well worth the effort.

From what I've been able to tell from the windoz TK/TCL, it uses
a small (about 8k) interpreter (shell) to interpret the text scripts.
Presumably this interpreter calls routines in the lib files (100 - 400k)
You can see the routine names (hundreds) with a text editor, and
there is a book available with details about calling these routines
via a C program.
My guess is that a Euphoria include file could be written to interface
with this library also -- converting Euphoria i/o to c function calls, and
adding all the windoz management functions.

Actually, there are a number of languages that incorporate Tk in a =
fairly "pure" version - Python, for example. But the Sun code is the =
only multi-platform source that I've been able to find, and that version =
definitely requires Tcl.

You could probably even hack into the Tcl/Tk DLL and set up your own =
interpreter session. The routines are well documented. I had considered =
this, but couldn't figure out how to link Euphoria functions as =
callbacks to the Tk widgets.
If Robert wanted to link to the Tcl/Tk, he could probably hide most of =
the Tcl details and make it look like "pure" Tk.
But there are some features about Tk that I am less than excited about - =
many of these reflecting Tk's X Windows origins.=20
Sun's Win32 window manager seems fairly inept at placing windows =
sensibly on the screen, and almost all the Tcl code I've run across were =
written by people with 20 inch screens. Resizing a window informs the =
geometry manager that the widgets in the window need to be rearranged - =
something disconcerting to Windows and Macintosh users, who are used to =
their controls staying in static positions.
On the other hand, Tk has some *very* powerful graphic routines - I =
wouldn't want to volunteer to rewrite them.
