Can two wx.Panel (s) overlap and the upper be transparent?

Greetings once again,

My goal is to have a (simple, kiosk application like) image viewer with only a few buttons on top of it (next image, previous image, exit).
My idea this morning was to use one wx.Panel to display the image (a no brainer in the meantime) and a second panel which is transparent in the first place overlapping the first panel and having only those few buttons.

The question is, can two panels overlap (I think they can) and is it possible for the second panel to be transparent so the content of the first panel remains visible?

SOLVED: style=wx.TRANSPARENT_WINDOW
