Answer 1

EDIT: just like i said HERE

What you can do is to create a alphatransparent form that draws the PNG and position it at the correct location and bind move etc.

http://www.codeproject.com/KB/GDI-plus/perpxalpha_sharp.aspx

PerPixelAlphaForm transparentImageForm = new PerPixelAlphaForm();
transparentImageForm.SetBitmap(<IMAGE GOES HERE>,<OPACITY GOES HERE>);

//opacity is the opacity that the image will be drawn with, a value of 255 = all transparent parts will be alpha/transparent just as much as the original PNG etc..
and you can put a timer that calls SetBitmap and changes the Opacity to fade in/out the image on the screen

And you can generate the text (on the fly) in a nice way with code from THIS article
and pass that image to the SetBitmap of the AlphaTransparent form.

EDIT: OR GO TO WPF.
