Two separate programms accessing a SQLite file

Hello,
I am developing an MVB application which uses a SQLite data file and will go into a multi user environment. I would also like to develop an completely separate application in a different language which will access the same SQLite data file. It is most likely that the additional application will only read the SQLite data file and then interact with an external hardware device based on a record in the data file. Having said that, I may consider having the additional application write something back into a field in the data file confirming that it has worked correctly and time of the event, that sort of thing.
Is it okay for multiple different applications to access a single SQLite file and even for both to write data to the file. I hope that makes sense.
Thanks, David.
