looking where to start

id like to made some hardware (a midi controller) for windows 7
where to start

Such a thing would probably see you have to learn a fair bit of electronics, a fair bit of programming and a fair bit about midi if you were going to go manual.

Instead I would consider picking up a teensy++ and fiddling with something like http://www.pjrc.com/teensy/td_midi.html
What you want your midi controller to ultimately be remains up to you but you can pick up things like https://www.sparkfun.com/products/7835 and variable resistors are not exactly hard to come by either.

well what i had in mind has a dj miidi where all the components where wireless sono you can
have you eq platers ect any where you want

Wireless in personal projects tends to make things nominally harder- with the likes of teensy hardware (and to a lesser extent arduino) you can do more or less whatever you like on USB interfaces and older ones like parallel and serial are open almost by default.

Anyway for wireless you have two main options as I see it-
1) you go conventional wifi (be it adhoc or otherwise) and either use a network protocol (I would probably go for netcat and convert upwards although I am not so up on my midi and given things like http://dsmidiwifi.tobw.net/index.php?cat_id=1 exist for the DS you might be able to go higher level) or make a keyboard and transmit conventional key presses from your nice pad you make. I am not sure what is available on the lower end "hacks for fun spectrum" right now (ethernet is one thing but wireless...) other than looking at things like the xbee which is not wifi in the traditional sense but should be enough for what you want.
2)You go bluetooth, there are various devices like https://www.sparkfun.com/products/9358? which can be used with the likes of the arduino. The price tag for such things is pretty high but you can do things like http://axio.ms/projects/btm400_6b/ for a lot less. I am not well versed in bluetooth though (around here we trust in wires).

If the above two do not do it for you then you are left mainly with proper radio or IR (do not do IR).

My advice right now is build one that works over USB and then adapt it to wireless afterwards aka break the project down into chunks/milestones- if you are not already at least partially versed in the components of the project and electronics in general you are going to cause serious trouble for yourself.
