  "fyne.io/fyne/v2/app"
  "fyne.io/fyne/v2/canvas"

func main() {
  myApp := app.New()
  myWindow := myApp.NewWindow("Circle")

  // Create a blue circle
  circle := canvas.NewCircle(color.RGBA{R: 0, G: 0, B: 255, A: 255})
  circle.StrokeColor = color.Gray{Y: 0x99}
  circle.StrokeWidth = 5

  // Create centered text
  label := widget.NewLabel("Go!")
  label.Alignment = fyne.TextAlignCenter

  // Stack text on circle
  content := container.NewStack(
    circle,                     // background
    container.NewCenter(label), // centered label
  )

  myWindow.SetContent(content)
  myWindow.Resize(fyne.NewSize(250, 200))
  myWindow.ShowAndRun()
}
