Get A Resizeable Window That Contains 2 Lines That Are Both Resizeable And Rotateable?

For this application, I need a resizeable window that contains 2 (two) lines (In a cross hairs design) that are both resizeable and rotateable. I need them both to rotate at the click of a button (The button is on a BubbleBar, but the code is the same for a normal button control). I also need them to resize with the window (It has to be accurate). I have tried using LineShapes from the Visual Basic PowerPack, however the amount of trigonometry involved with this solution was too much for me to implement and understand.I also tried using a WPF ElementHost to accomplish the same thing, without luck. I tried using the RenderTransform property of the WPF Lines to rotate them, but I could not apply both that and resizing to these lines.
