I find the solution, I can change button style to make it like label

public class TestLabelLikeButton : EditorWindow
{
    [MenuItem("Test/Label Like Button")]
    public static void St()
    {
        var win = GetWindow<TestLabelLikeButton>();
        win.Show();
    }

    private void OnGUI()
    {
        GUILayout.Button("Btn", GetBtnStyle());
    }

    GUIStyle GetBtnStyle()
    {
        var s = new GUIStyle();
        var b = s.border;
        b.left = 0;
        b.top = 0;
        b.right = 0;
        b.bottom = 0;
        return s;
    }
}

Are you trying to make a UI button? If so, you first need a canvas. From the top toolbar:

GameObject → UI → Canvas

then you can add a button:

GameObject → UI → Button
