Go GUI

there are several Go packages that wrap the Windows GDI functions in a more idiomatic and less verbose interface. Here are some of the better options for creating a chess GUI:

• Fyne: A cross-platform GUI toolkit that works on Windows and abstracts away the low-level details:

go get fyne.io/fyne/v2
fyne-io/fyne: Cross platform GUI toolkit in Go inspired by Material Design @GitHub

• Walk: A Windows-specific GUI toolkit for Go that provides native Windows GUI capabilities:

go get github.com/lxn/walk

lxn/walk: A Windows GUI toolkit for the Go Programming Language @GitHub

• Gio: A cross-platform GUI library with immediate mode rendering:

go get gioui.org

Gio UI

• Ebiten: More game-focused but excellent for something like chess:

go get github.com/hajimehoshi/ebiten/v2

ebiten package - github.com/hajimehoshi/ebiten/v2 - Go Packages

hajimehoshi/ebiten: Ebitengine - A dead simple 2D game engine for Go

even without packages, Go can access Windows (and other OS) GUI features

Here is a super-simple but functional Go GUI "Hello World" program.

package main

import (

    "syscall"

    "unsafe"

)

var (

    user32      = syscall.NewLazyDLL("user32.dll") // Loads the user32.dll library dynamically

    messageBoxA = user32.NewProc("MessageBoxA")    // Gets a reference to the MessageBoxA function

)

func main() {

    messageBoxA.Call(

        0, // NULL for the parent window handle

        uintptr(unsafe.Pointer(syscall.StringBytePtr("world!"))), // message text

        uintptr(unsafe.Pointer(syscall.StringBytePtr("Hello"))),  // title

        0, // type of message box, default

    )

}
