But Sycamore does have ambitions to have native GUI support as well. I'm currently looking at GTK, Iced, and GPUI and see if it would be possible to add Sycamore support. This would make it possible to create GTK, Iced, or GPUI apps using building blocks from Sycamore.
FWIW, as an iced user, personally I'd prefer to write iced and use something like sycamore to build for the web rather than the other way around
I feel like combining the drawing layer from one of these existing native UI frameworks with Sycamore could be interesting in reducing some of the boilerplate with GTK, Iced, GPUI, etc...
