Well, competition is good ... 

Here's why I went off to do my own:

-- I couldn't understand how bond worked.  It wasn't documented,
   and reading the code didn't help.   I'm impatient; if I can't figure
   it out in a day or two, I skip.

-- The examples didn't work out of the box, and the instructions for
   making them work were out of date.  (although DWI probably suffers
   from the same problem).

At the time, I was under a time crunch, so after much agonizing &
hand-wringing, going my own way seemed best & easiest.

Now, if you can explain the errors of my ways ... then ...

Well, anyone designing the web interface has to understand that the web
is not as flexible as the native interface.  This is a fact of life;
there's no simple technology solution that fixes this.  People have been
bitching about this from day one, but the reason teh web took off was
that it *was* simple.  

Later, javascript, and after that, java applets tried to 'fix' this
problem, but not with much success.

> and somethng like a gtkclist, 

gtkclist is fundamental.  but instead of trying to emulate its
callbacks, you need to create seperate web representations for it.
If its only for displaying data, its enough to just have a table.
If you need to select a row, or mmutiple rows, that is something else
again.

Well, yeah, that's called 'javascript'.  But I never liked websites that
require javascript.   But if its important to you, that's the way to do
it.  Its a *lot* easier than java.
