An airport or a country cannot come up with their own codes, they all must be co-ordinated with IATA and ICAO.
Actually incorrect.. for the rest of the world it works the following way
LGW = EGKK
E = Europe North
G = Great Britain and N Ireland
KK = London Gatwick = LGW
LL = London Heathrow = LHR
SS = London Stansted = STN
GW = London Luton = LUT
CC = Manchester = MAN
NT = Newcastle = NCL
NV = Durham Tees Valley = MME
Where the designator is 2 of the same letter this indicates it is a filing centre. The 3rd character of the ICAO in the UK indicates the filing area. All Scottish airports are EGPx, all N Ireland airports are EGAx.
FRA = EDDF
E = Europe North
D = Deutschland
DF = Frankfurt am Main
ROM = LIRF
L = Europe South
I = Italia
RF = Rome Fiumicino
The first letter is always the regional designator, followed by the country (except in the case of New Zealand where it's NZxx anyway)...
