HDTV- Single Composite input- numerous older devices.

I purchased a new 3d HDTV and unfortunately, it seems like the manufacturers skip on the input options nowadays. It has 4 HDMI inputs, however, only a single component with yellow option. I have a playstation 2 and WII using analog, DVD player using component, and in addition, media PC that needs analog audio. Is it possible to hook all these up using cheap 2-way splitters? I am aware there is a cheap switch box, but would like to hook them up without flipping a switch, for convenience sake. Also, there are a lot of amplifier/splitters that offer 4 output TVs and one input device, however, not sure if this would work in reverse.
