It should work, what do you mean when you say 'i can't make it'?
To create an Aether portal, you simply make the same frame as you would with a Nether portal, but except instead of Obsidian, you use Glowstone Blocks, and instead of activating it by using a Flint and Steel, you simply pour a Bucket of Water somewhere inside the frame, and bing bang bong, you got an Aether portal.
If you're in Creative mode, simply go into your inventory, go to page 2 of items, click the Aether Blocks tab and the first block you should see is an Aether Portal block. You can just use that, it's pretty much the same.
