Formation
{V-nai}かなあattaches to ない-form
Variant notes
- ないかな — the short vowel, same wish with less longing in it — a passing thought rather than a sigh（誰か気づいてくれないかな）.
Notes
about what they will do themselves goes to 〜たい instead. The tail has no
polite form either; upward the same murmured hope goes 〜ないものでしょうか.

かな wonders and leaves the answer open; ないかなあ freezes the negative and turns the wondering into wanting, so 週末になるかなあ can only ask whether the weekend will come, never wish for it.
といいね hands the wish to the listener and is what you say TO someone about their cold or their exam; ないかなあ is muttered with nobody addressed, which is why it closes on なあ and never on ね.
てほしい states the want outright and names who should act (手伝ってほしい); ないかなあ leaves it hanging in the air, so it can angle for help without ever putting the request to anyone.
Lookalikes
One negative-question skeleton, two speech acts — 手伝ってくれませんか is put to the listener and waits for an answer, 手伝ってくれないかなあ is addressed to nobody and expects none.
