You can't do the approach you are suggesting, because the Maya commands API
doesn't have a concept of a "Window" instance that it can return to you.
When you write a command plugin you are defining a Maya commands-style
call, which can take some parameters, do some work, and then return values
that are supported through the setResult() methods. Instances of custom
python classes are not one of those things you would be returning. What
should a MEL user expect to get back in the results? What would a C++ user
get back?
If you look at how the rest of the Maya commands work, you will see they
deal in terms of string paths to objects, and accepting those in other
functions to perform edit or create operations.
