I have been searching for ages in my swamp, but I can't find a witch hut and I don't know how how to build one.
Does anyone know of a surefire(100% acurate) way to find witch huts?

Where witch huts are placed depends on your world seed.
You can find out the seed by typing /seed in the console.
To find the witch hut, you can either calculate the coordinates by hand (too complicated); or use an tool like AMIDST:
The turquoise biome is a swamp, and the purple icons are witch huts (marked with red borders in my image), the house icon is the world spawn. You can find out coordinates of a place by hovering over it with the mouse; the coordinates will be shown at the top right.
If you are looking for a seed with multiple which huts at the same place, you might want to check out this thread: Quad Witch Huts
For building an witch hut I would recommend this tutorial: YouTube Video
1There is not a 100% sure way because huts are spawned in at random. Also, you cannot build one either. The spawning space that actually spawns the witches are in a hut within a 5x5x4 dimension but don't take my word.
