几步，写出一个 Go GUI。

mkdir hello-goui
cd hello-goui
go mod init example.com/hello-goui
go get github.com/golang-gui/goui@v0.4.0

请按照 https://github.com/golang-gui/goui/blob/main/skills/INSTALL.md 的说明，安装 GOUI 应用开发 Skill。

package main

import (
    "fmt"
    "log"

    "github.com/golang-gui/goui/theme/modern"
    "github.com/golang-gui/goui/ui"
)

func main() {
    count := ui.MakeState(0)
    err := ui.Run("com.example.Hello", func(app ui.App) ui.RootView {
        return ui.Root().
            StyleSheet(modern.FromSettings(app.Settings())).
            Windows(
                ui.Window("main").
                    Title("Hello GOUI").
                    Size(480, 240).
                    Content(
                        ui.VBox(
                            ui.Label(fmt.Sprintf("Clicked %d times", count.Get())),
                            ui.Button("Click me").OnClick(func() {
                                count.Update(func(old int) int { return old + 1 })
                            }),
                        ).Spacing(12).Padding(20),
                    ),
            )
    })
    if err != nil {
        log.Fatal(err)
    }
}

CGO_ENABLED=0 go build -trimpath -ldflags="-s -w" -o hello-goui .
