[Python3] tkinter, 緊急停止ボタンの作成に関して教えてください

■やりたいこと
1、　ラジオボタンにて帯域を選択したあと、チェックボックスを選択し、
【測定開始】ボタンを押した際に、常に前面に表示されるウィンドウを作りたい。

2、　サブウィンドウの中に「停止」ボタンを作りたい(ボタン作成のコードは作成したが反映しない)

■現状
【測定開始】ボタンを押した際に、一番最初に表示させたいサブウィンドウが、一番最後に表示されてしまう。
サブウィンドウの中に一つボタンを作りたいのだが、コードが反映していない。

イベント処理が終わらないと描画処理が動けないため、処理が終わったあとにウィンドウが表示されます。
時間のかかる処理を別スレッドにして、イベント処理をさっさと終わらせるといいです。
