how to create a database to store values and strings?

I have built a GUI file and I need to store Longitude and Latitude of specific airports in a database so that i can call them in my GUI, can anyone help me with that? I prefer to make a .db file.

Kyana - what is the format of your db file? Is it just an ASCII text file with latitude and longitude pairs (and maybe airport info) that you wish to read from, line by line?
