You really need to do some reading. I suggest the FAQ Emporium, for starters.
Although, what you're looking for is a bit buried, so I'll help ya out:
List of front-ends/other useful apps
That thread lists a lot of software that people use (Frontends and other support software) with links to the authors' websites. If the website doesn't contain the information you want, you can always contact the author.
And I know for a fact that FP is based on WMP.
I also know for a fact that if you'd done a wee bit of research, you'd know this.
Use the search function on these forums. It's your friend.
