Well, there is no special tutorial.
it depends if it 2d, 3d, opengl, SDL...
The simple way is to use Lazarus in Windows.
If use any component, just check on the web that they work with Linux.
Or install a linux in windows (VMWare is free, ubuntu is easier to install than windows, and Lazarus can be installed in 2 clicks in Linux)
I don't have to much spare time for the moment, but i'll try to code a little demo to show how simple it is
