If your expectation is something like Lazarus or Delphi, with a GUI builder (with company support, or like C#/.NET) then I think you’ll find nothing similar for Julia. FYI this thread (you can use Julia with other languages, e.g. Delphi, though likely not many have done so before you):

You can expect (I’ve seen up to 100x claimed, also elsewhere, vs Delphi, despite it compiled, and not a slow language/compiler) speedup in runtime with Julia (maybe the reason you adopted Julia, why did you? Did you read misleading claims about the ecosystem?), but development time for the GUI is likely worse. I don’t know which GUI toolkit is best for Julia (haven’t used any of them). None of the GUI options, or web based options, have company support with Julia (one did, for web, then Julia support made unofficial again). Mousetrap is based on Gtk, but understand made simpler, why I suggested it over Gtk or Qt. Qt/QML is another option, has company support (when used natively, i.e. with C++), and I believe it has a GUI builder.

> I am continually impressed at what Julia language (pyjulia) can do with making julia calls from within python.

If you want to make the GUI with Python, then I suggest PythonCall.jl, not older pyjulia.

> I think Julia does not like Windows.

I don’t think that’s true (only minor issues, and Windows not neglected, despite Julia developed first on Linux only), if anything Windows or (its) virus checkers do not like Julia… slowing down, but such Windows issues affect mostly any language equally.
