Making Applications instead of exe's and installing .net framework

Question

how do i make an application in visual basic? my friend who has vb5 just needs to use an application setup wizard, but i (a) don't have it (b) don't know where to find it can anybody tell me where i can find this? my other problem is this, only about half the people i give my programs to have .net framework installed on their computers, therefore they can't use my programs. are they able to install .net framework without vb and stuff? if so, how would they do that so they could use my programs. thanks for any answers
