Will "WxBookCtrl>>#insertPage:page:text:" help? It takes the desired
page index, the page (panel) to insert, and the tab label for the page.
  So could you create all your pages at app startup, hold them in a iv,
then use this call to insert them when they are needed? Or does deleting
the page from the notebook blast the handle for that page?
