I think you mean Oracle Developer Forms..
you need to install Oracle Forms 9i or 10g to build a form...and to use it you need to read a book or take class course in Developer...
I hope this is what you look for
BlueMan

I want to Ask about if the Oracle Application Server is free or priced ?
and also if I have a database and want to host it on a Server, how can I put in and what should I use to do so? and what should be installed on that Server ? what Software ( oracle Database or Application Server only or what?)

if anyone can please show some information for me as a bigginner to use oracle would be very appreciated..

Thanks...
