dilesha, cPCreator is no longer supported by Jonny, the rights were sold awhile ago. He now has another project called "The Hosting Tool." It's his current script, and it's supposedly advanced from cPCreator.
Also, answers to your somewhat odd questions.
1.) If you used PayPal, currency would automatically transfer.
2.) Currently PayPal is only supported, and what sort of payment processing website goes directly to bank? Wire transfer is my only though, but that's unsafe and not many people would do that.
cPCreator still holds a great brilliance in the hosting areas as it does work for paid hosts. So far I do not think (but never used) The Hosting Tool supports paid modules. But you may want to take a look, as I have never used it. cPCreator equals to iDev's iHost/iPanel. It's not as good, but most certainly a great competition to WHMCS.
Although cPCreator V2.8 was released about 3 or 4 days ago, we do not know if it will be as good as the originals due to it not being developed by Johnny anymore.
