I got an Idea but i wanna know if it would be hard 2 do:
If I had like a GUI based game with video like a computing (have it based on somebodies computer) game, but have other aspects like living someones life... while staying out of trouble... but in the end getting in trouble... and then keep the story like that
Huh?
You'll have to be much more specific.
This sounds kinda like those Japanese dating sim games from your somewhat vague description :P
Some of those have a mock OS like set up, with email and stuff to and from characters, as well as other locations where you can speak to characters, play minigames and the like.
I guess it wouldn't be too far removed from the more standard adventure game set up so no, it wouldn't be that hard to do. Although like Ryan said you'll have to ask more specific questions about what you're trying to achieve exactly.
