The last one I did was using Fyne in Go, which is quite cross platform but its software drawn not native. Its targeting phones as well so its cross compatibility is very good but at the cost of giving you the full complexity of desktop applications, it does not have a highly capable table view for example. Since its written in Go this is what you will develop in.

Otherwise I think its QT and GTK on C/C++ as the other option across the desktop operating systems, neither is native on anything but Linux but they also look OK but I think a lot of people would rather avoid C nowadays for application development.
