certainly, they can be.

futile is more like one's efforts don't make a difference at all.  Like trying to change a planetary society that is deaf to you.

Ineffective is more the focus on the interaction itself.  Like blowing one's breath on a building, and expecting it to move.

Futile is more the lack of result; and ineffective is more the lack of ability.

There can definitely be emotional attachment/fixation on either.
