Pen Input Possible?

I am currently making tutorials on C , for which i need something from.which i can write on pc . Like a pen input , like wat ever i write on my Note would be detected by my pc. In short , can i use.my note as pen input for pc.? Is it possible?
Is there any application? Or ny sort of drivers that could be installed or any tweak to be done in kernel?
Looking forward to buy a pen input device , but wont be bad saving some rupees if i can use note..
Thanks in advance
