Welcome Jalien. As they've asked above, I'm not sure if you're asking what writing software to use, where physically to write, or where you can find the tools to write.
If you ware serious about writing, you are going to need to acquire the tools of the trade. It is possible to write your novel using pen and a notebook, then transcribe it on a borrowed computer, but what happens after you submit it and the agent or publisher asks for edits. you'd have a big hassle making those changes on borrowed a computer.
A desktop PC that will do everything you need can be purchased for less than $500, including the printer. Add $200 if you want a notebook PC. Christmas is coming.
If you are a student, you MAY be able to obtain a free academic version of MS Office for your new PC, check with your school. If you are out of school, OpenOffice is free and many writers swear by it.
If you are asking about a physical place to write, pick a place where you can get some work done without interruption. It is WAY too easy to allow yourself to be distracted (like posting to this forum) when you should be writing.
Welcome again and good luck.
