Virtual PC for the Mac has been pretty much discontinued, as you can now install Windows on all new Macs, either by dual booting with Boot Camp or virtually with numerous tools, including Paralels which is much cheaper tha Virtual PC was.
If you have an older PowerPC Mac then Virtual PC is the only realistic option I think. There are/were a few odd open source projects, but last I looked don't think they were really up to 'real world' use.
If you're not ready to upgrade your main system, you could look into a Mac Mini or MacBook with any of Boot Camp, Parallels, VMWare or maybe CrossOver; or else a real physical PC and a KVM switch.
(My own solution has always been to buy, beg, or borrow used PC's from friends when they upgrade.)
Do not buy VPC! If I were you, I would 1) sell your G5 on ebay, which depending on model would fetch roughly £300 or more. Then 2) save the money you would spend on VPC and buy a new Mac!
VPC was only ever good for basic tasks, such as writing documents - it was never meant for anything intensive such as gaming, and with the amount of CPU that a modern version of say, Dreamweaver needs, it makes it unlikely that you would enjoy your experience of using VPC!
Both Parallels and BootCamp only run on Intel machines due to the difference in chip architecture. Seriously, go and get a new Mac!
