As output from laptop is too small to operate speakers of any kind.
You need to go through an amplifier first, as output is only equivalent of a pre amp output.
However leads with jack in and phono out are freely and cheaply available from Maplins or most friendly local computer stores.
As regard speaker wire, any twin cable will be OK.
Again you can purchase correct cable easily with whatever ends you want and cheaply from local HI-FI or computer store, or Maplins.
Hope this helps.
