ETFs without dividend payment

Not sure if this is an obvious or stupid question...

I want to invest in an ETF I can leave alone and don't have to worry about declaring any capital gains to the tax authority. So that any gains are only taxable when I sell.

I don't mean to cheat. But my current marginal tax rate is quite high, but will be much lower when I retire.

EDIT: somebody mentioned ETNs. But there is I am concerned about the dependability of the issuer as there are no real assets.
