Yes, you can play your wii/gc games across 3 monitors as one resolution, provided you have a correctly supporting graphics card and a fast enough processor.
AMD Eyefinity:
5000 series or newer
Will need an ACTIVE displayport adapter if you do not have any displayport monitors. Please do your research, a regulra passive adapter is cheaper and will not work.
Nvidia Surround:
You will need to either have 2x 500 series in SLI
**OR**
1x 600 series (recommended over 2x500 series)
You need to set up the eyefinity/surround on your desktop FIRST before you enable it on dolphin. Also OpenGL does not work well with this type of set up, you will need to test DX9/DX11 with various levels of Vsync/Anti-Aliasing/Antiscopic Filtering and may find DSP LLE makes things better for your game as well.
DJ hero 2 was the hardest to get perfect and required me to overclock my cpu a little more to 4.2ghz, install the DSP LLE, and run Vsync so that the sound/video was matched and consistent.
My current computer:
Intel i5-3570k @ 4.2ghz oc (stock voltage, stock heatsink)
4gb PNY 1600mhz DDR3 Cas8
60gb ocz agility 3 ssd/WD 1tb
Asrock Z77 itx motherboard
Asus HD6870 1gb video card
Siliverstone ITX case/450w psu combo
Win7 Home Premi x64
IVT (CSR) mini USB bluetooth dongle (cheap $1-2 type)
USB mouse/keyboard
3x Dell U2410F ISP monitors - 1920x1200 resolution each, 5760x1200 total
Using real wii controller (black)
Using real wii DJ hero turntable
Logitech 5.1 surround sound working
Logitech G930 wireless headset (usb dongle) working
Software:
Current Dolphin 3.0 - 776 + DSP LLE enabled
Toshiba Bluetooth stack, works better than bluesoleil for me
Catalyst Control Center (CCC)
