Is there anyway of syncing my Google/Gmail tasks with iOS reminders?
I've created a service called Tasket which Syncs iOS Reminders with Gmail Tasks. I do this by emulating a Microsoft Exchange server - iOS supports syncing Reminders with Exchange.
Tasket is currently in beta. I'm just waiting on Google to increase their API quota so I can add more users. Hopefully people find it helpful. I like the native Reminders app.
Sorry to be the bearer of bad news but no, not currently.

I have not heard of a way to sync...but 2nd best would be to view them both in the same place. Fantastical gets great reviews for this...see Fantastical
Gtasks is subpar. The biggest reason I like iOS Reminders is it's one of the best things that SIRI does well. I use it all the time. If gTasks were capable of acting as an intermediary between Reminders and Google Tasks then it might be a good product, but at the end of the day, it's a stand-alone tasks app that does not take advantage of SIRI. This coupled with the deception of listing it as "free" on the AppStore but requiring you to pay for it later in-App...not cool. I am all for paying for a good app but give it to me straight. At the end of the day it does not have what I want in a tasks app.
GTasks will allow you to manually import iOS Reminders to Google Tasks, but there is no 2-way sync. http://itunes.apple.com/app/gtasks-hd-google-tasks-go/id428249408?mt=8&ls=1
