Firstly, this should be in the support tickets thread.

Secondly, if you look at the support tickets thread, you'll easily see the second thread on it is called "Minecraft not working? TRY THIS FIRST" with the answer to this problem. Also, the most recent post in the support tickets is this same issue with a nearly identical crash log AND a solution.

But whatever, To fix this, just put this: http://files.minecraftforge.net/LegacyJavaFixer/legacyjavafixer-1.0.jar in your mods folder and try reopening Gulliver.

And moved!!  Don't infringe on my Learning section if you're not there to learn.  :<

(Also, thank you A4!) ^^

Thanks
