Launching 2 applications with one launcher

Is it possible to code a launcher to launch two applications with one laucher and if so, can you tell me what I gotta type (at least the "define" part). I searched like a bloodhound on the NSIS website.

Note that I'm using NIS Edit Portable (still in beta).

I won't tell you what its for right now but trust me, your gonna know why as soon as I find out.
