Yeah, more literally it's like "It would be good if..."
Adj/Verb+(으)면 좋겠다 is how you would build a sentence.
I hope the weather is nice tomorrow = 내일은 날씨 좋으면 좋겠어
I hope there's a lot of food = 음식이 많으면 좋겠어
I hope you did well [on a test] = 잘됐으면 좋겠다
I wish I were dead = 죽으면 좋겠다
You only need the (으) if it ends in a consonant. For example if the verb was 가다 to go, it ends in a vowel so you say "가면 좋겠다"
