They have one year to wish them back after then die or they run out of time. Can Bulma, within a year, single highhandedly build a spaceship in a world with a completely destroyed infrastructure? That's a pretty big feat. Where is she going to get all these materials refined and build the thing? Where can she do research? Where can she even reference old info without an internet or libraries? Keep in mind her dad was the one to build the original, she cannot fly and has no help. Where can she get tools and reinvent the ones she will surely need to build this one of a kind ship? On top of all that have time to run for your life from psychotic androids, taking care of your baby son while grieving over your dead lover and best friends.
My point is she could not have built a spaceship within one year of the planet getting purged and the Z-fighters dieing. Capsule Coorp was obviously in a major city which would of got wrecked right away. Her only bet was the time machine and patience. Having a spaceship would have of served little purpose once the one year deadline to wish the fighters and all the people killed back passed. Also the dragonballs would not have been able to bring Goku back anyway since he died of a sickness and without him the whole plan is shit. They can't wish the andriods away or Gero either because you can't wish away someone stronger the the creator of the balls which they all are.
Edit: Typing that first paragraph out like that made me just realize how boss future Bulma is.

The generalist looks outward; he looks for living principles, knowing full well that such principles change, that they develop. It is to the characteristics of change itself that the mentat-generalist must look. There can be no permanent catalogue of such change, no handbook or manual. You must look at it with as few preconceptions as possible, asking yourself, "Now what is this thing doing?" -Children of Dune
The dragon ball wikia doesn't make it clear whether or not the Namekian balls have a time limit, but I'm pretty sure they are still unable to bring back Goku due to his natural death. There is still the issue of making the ship, finding New Namek, traveling there, wishing back the others, and hoping the Androids don't kill them again while you travel back to Earth. I also assume the Hyperbolic Time Chamber is probably inaccessible due to the lack of guardian, or that the lookout may have been destroyed since it's a known haven for the Z fighters.
Based on Vegeta's actions during the Android Saga, Future Vegeta probably wasn't even trying to save the Earth, he was probably just looking for a fight.

bills is an awesome breakdancer

new fusion in the next movie
I'm assuming you're doing another April Fool's, as I'm pretty sure Trunks is still a kid in the movie, and the purple hair indicates that the fusion is at least part Trunks.
