[Gtk-sharp-list] Buttons & Cairo graphics

Hello, 

I have a fairly good background in programming (scientific computing) but
I'm completely ignorant when it comes to writing GUIs and I wondered if it
was easy to draw a shape with Cairo and use it as a button. That is; 

1. I draw a shape, e.g.; the rectangle in the cookbook
(http://www.mono-project.com/Mono.Cairo_Cookbook)

2. The color of the shape change when the mouse pointer is moved over it.

3. You can click on the shape to do an event X. 

Also I wondered if it was possible; 

4. To write a GUI with Mono/Cairo and using the code for Linux/Mac versions,
but creating a windows .exe using Visual C# Express without modification to
the code (that is, I take the mono project, open it with visual C# express
and try to compile it). 

5. To create complex shapes like regions in a map, and still to be able to
click in one of these complex regions to do an event X. 

I only need to know these things are possible. If a better option than Cairo
is available I'm also interested, but I really like the idea of using a
vector-based library as it allows to resize images easily (well, in theory).
The other alternative is using C++ with Qt, but I'm not a big fan of C++ and
if Mono can do what Qt can do, I'd prefer Mono ! 

Thank you
