It allows PC gamers to enjoy games for these two consoles in full HD (1080p) with several enhancements: compatibility with all PC controllers, turbo speed, networked multiplayer, and even more!Dolphin is available for Linux, MacOSX (intel-based), MS Windows and Android.

For playing games you can directly play from your wii games iso / dvd. Here's the UI of dolphin emu:
Make sure your PC/Laptop have meet requirement of Dolphin, if not the wii games will be slow. On my Laptop Dell Inspiron N4110 Core i3 2.3 Ghz with ATI HD 64xx 4GB ram, some games run very lag on 3D, but for 2D it run fast. For see compability you can check on dolphin sites below.
Enjoy your Wii/Gamecube games on PC/Laptop.. :D
