If you go the virtual or dual boot route, yes. You will then have, effectively, a full native install of windows on your Mac and you would install and use windows apps just as you would on any windows PC.
The process is to first install the virtual machine software - VMWare Fusion I think is currently about $50, not sure but I think Parallels is $80. Once installed, you would launch the virtual machine software, create a virtual machine - you would need to give it windows disc space which will be a virtual disk, so just a file on your Mac hard drive, also assign it RAM to use and so on. Once the virtual machine has been created by the software, you would need a Windows install disc, and you would install Windows. After that, you would use Windows in that virtual machine just as if you were sitting at a dedicated Windows PC. When you do not need Windows, you would just "shut down", then close the virtual machine software.
Check out the web sites for VMWare Fusion and Parallels as they have some good documentation.
You can also use Apple's own Bootcamp to partition your hard drive, install windows on the new partition and then you select which OS, OS X or Windows, to boot your Mac into when you start it up. The downside of that is you cannot run both simultaneously. With the virtual machine, you can just toggle back and forth, as the Windows virtual machine is really just another piece of software running on your Mac as far as OS X is concerned.
