Is WPF right for my app?

I am in the process of determining if WPF is right for my app. My app requires that my main entry form look like a paper form for example a IRS 1040a. I can draw this form very easily on a Canvas, but because the canvas is position based, it doesn't resize with the screen, however I need to be able to resize the whole canvas based on screen size. I have tried the grid and stack panel but the wrapping and resizing doesn't work for what I want. I have to maintain the look of the form and maintain the aspect ratio as well. Any suggestions or where to look for examples would be greatly appreciated.
