Hoping I understood your question correctly :
If by desktop you mean like windows or mac, then you could use a remote client like splashtop remote/vnc etc.
or there is another app called virtual tablet that makes your note a virtual tablet for your computer (though pressure sensitivity does not work, but other features can be used)
However if what you are asking is all to do on the note itself then there are a plenty of apps that let you do that and have pen support.
for example in pre installed s-note you can switch between writing pen/pencil/ highlighter / eraser.
I mostly prefer handwriting recognition in the samsung keyboard as with that I can do a lot more in most of office like apps.
