[go-nuts] [ANN] goey - Declarative, cross-platform GUIs

[Robert Johnstone]

This is an initial announcement of goey, a package for declarative, 
cross-platform GUIs.  The range of controls, their supported properties and 
events, should roughly match what is available in HTML.  However, 
properties and events may be limited to support portability.  Additionally, 
styling of the controls will be limited, with the look of controls matching 
the native platform.

A minimal example of a complete application can be found at 
https://godoc.org/bitbucket.org/rj/goey/example/onebutton.
