If you look at some example PayPal doante buttons you can probably figure out how to change the amount in them. The rest is just about generating a new URL for them to click on and sticking that inside a GWT object. You might find it easiest just to use a provided paypal widget - they actually have the ability to have a field for entering the donation amount. Why reinvent the wheel?
When it comes to accepting credit card payments, PayPal is a nice easy place to start since they take care of everything. If you want to do this using another system, you'll have to look at how that system works. Google Checkout, Authorize.net, WorldPay, Nova, InternetSecure, PSiGate are all companies that let you sign up for a merchant account and payment processing gateway needed to process credit cards. Credit card processing can be quite involved due the security requirements around credit cards.
