[no subject]

this application consists :
1- To create a main window without a border
2- To put an image in the background of this main window
3- to add many widgets, like buttons or other images, in the main window 
above the image put in the background

My problem is that I can't mix the 3 parts.

Could you please send me a few advises or a few samples which could help me 
to realise it ? I thank you in advance

yours sincerely

Mr Stephan REDON
