GUI in the Scene View.

To use this example, place this script in the Assets/Editor folder:

using UnityEngine;
using UnityEditor;

[CustomEditor( typeof( DummyButton ) )]
public class DummyButtonHandleEditor : Editor
{
    public float arrowSize = 1;

    void OnSceneGUI( )
    {
        DummyButton t = target as DummyButton;

        Handles.color = Color.blue;
        Handles.Label( t.transform.position + Vector3.up * 2,
                t.transform.position.ToString( ) + "\nShieldArea: " +
                t.shieldArea.ToString( ) );

        Handles.BeginGUI( );
        GUILayout.BeginArea( new Rect( Screen.width - 100, Screen.height - 80, 90, 50 ) );

        if( GUILayout.Button( "Reset Area" ) )
            t.shieldArea = 5;

        GUILayout.EndArea( );
        Handles.EndGUI( );

        Handles.DrawWireArc( t.transform.position, t.transform.up, -t.transform.right,
                180, t.shieldArea );

        t.shieldArea = Handles.ScaleValueHandle( t.shieldArea,
        t.transform.position + t.transform.forward * t.shieldArea,
        t.transform.rotation, 1, Handles.ConeCap, 1 );
    }
}

...and attach this script to the object which you'd like to attach the handles:

using UnityEngine;


[ExecuteInEditMode]
public class DummyButton : MonoBehaviour
{
	public float shieldArea = 5;
}
