Custom Message Box in Windows CE

I need a substitute for the standard MessageBox dialog. It is to work on a mobile device running WinCE. I want to display a yellow oval in the centre of the screen with up to 3 lines of text on it. The message is dismissed by a touch anywhere on the oval. Note that:- 1. It need not be draggable 2. It should operate as a modal window 3. No buttons are required 4. You can assume the text will fit the width of the screen, so text wrap is not required. The code should be in C# I have no prejudices about how this is implemented. It could be a function; a class; a dialog box; operate on repaint etc. NOTE There are a number of restrictions in WinCE compared with Windows Mobile. DO NOT BID unless you have experience of WinCE and a device to test your code on.
