PS, sorry about all the strange questions, im still new to this subject.
Yep, it's possible, but as you say it won't be much good for anything. The quality of the glass in not so much a problem as is the fact that with any simple lens you will get chromatic aberration and spherical aberration, no matter how good the quality of the glass.
