Default Contructing a balun for receiving antennas

Could anybody let me know how to contruct a bulun to match a longwire
antenna to a receiver. A step by step guide would be appreciated as I
am a non technical person.


Ummm... you don't use a balun to match a long wire. Balun means
"balanced to unbalanced". A long wire is unbalanced. So is the 50
ohm output from your radio. If the antenna were a dipole, which is a
balanced antenna, you might need a balaun, but not a long wire.

Search Google for an "antenna tuner" claiming to match any antenna to
50 ohms. There are plenty of construction articles online, but you
need to know if you're building a QRP tuner, or a kilowatt monster.
Some indexes:

If you wanna buy something ready to go, I like LDR automatic tuners
and MFJ for cheap tuners. Be sure to build or buy something that will
handle the frequency range and power output of your unspecified
xmitter.
