Tabbing this song

so instead of searching for tabs for a version of "When I'm 64" I'm using WS64's version and tabbing it. thats not my problem. I've gotten around 5 bars done but I use guitar pro and I don't want the note duration in the tab because I can play it different every time and I don't feel like going into triplets and what not. is there any program someone can suggest to make a tab that I just enter the numbers, I do not need to hear it. and is it bad that I wanna do this?
