Every 256 bit number is a private key,…
nitpicking mode: that's not true. there is a very very very small range of numbers, which do not lift properly on the underlying elliptic curve.

I wrote on article on how to create a Bitcoin Address with JavaScript. It's very in depth, and explains step by step the entire process. Hopefully it helps.
Yes, plz. I'm quite interested in this and would like to know more.

thanks..would you give me your bitcoin address?
The private key is a random 256 bit number. Every 256 bit number is a private key, but some are safer than others. You should use the strongest entropy source that you can get your hands on to generate them.
The public key is then simply pubkey = G * PrivKey. The catch is that * is EC multiplication in the appropriate modular elliptic curve field and G is the base point of that curve.
From there, it is just a matter of hashing and encoding to generate the address.
All of this is well published. Would you like some tips on searching?

I understand that to create a bitcoin address, one has to have a private ECDSA key first. What I don't know is how to take the corresponding public key generated with it. Are the private/public keys of ECDSA generated at the same time? Or is there any algorithm for us to calculate the public key based on the private one?
