I was wondering if a rogue, with haste applied, could cast booming blade on one action, do an attack on a second action, and use their bonus action to do an offhand attack.
No, because the additional action granted by Haste "can be used only to take the Attack (one weapon attack only), Dash, Disengage, Hide, or Use an Object action." Booming Blade is a spell, so it is not eligible for Haste.
The best way to use Haste as a Rogue is to use your second action to Ready an attack with a trigger that'll happen on another creature's turn. This lets you get a second Sneak Attack in the same round.
Right, but haste is adding a second action that you can attack with (and do the other things you listed.). So with your original action you cast booming blade. Then with the second action, via the haste spell buff (this is assuming the buff is already running) you make an attack, and since you have made an attack with a main hand weapon you could still make an offhand bonus attack.
To InquisitiveCoder: Yes that's 100% correct, I was just wondering about the above scenario being possible.

Yes, that works.

Filcat is correct.
