Winforms development on linux?

I am a noob here, so be patient with me.  Is there a way to develope winforms app on a linux system?  I am running openSUSE 10.3, mono installed, monodevelop, and I have even tried mwf-designer to no avail...  Anyone who is successfully developing winforms on linux, if you could let me know the steps I need to take to achieve this, would be greatly appreciated!
