Running a virtual machine with Windows 7 Pro on a MacOS

I've been a Windows guy for over a decade, but I've decided to switch back to Mac for a while. (There are a number of good reasons for doing this which I won't go into here.) Anyway, I can't leave the Window universe behind completely, I'll need my Windows development tools (Visual Studio, MS Access 2010 w/ VBA, MS Excel 2010 with VBA, and Dreamweaver CS5 (I'd prefer not to buy the MacOS version)). If I install good VM software on the Mac, can I run full versions of these programs on a full version of Windows 7 Pro? Or, will these programs and Windows 7 function but not function fully? What VM software is my best bet?
