Marker-Link

Dear OSM-devleopers,

it’s possible to generate and show a simple marker-link-adress in the export-function, additional to the iframe-code? That would be made it easier to use Openstreetmap also for people, who don’t have so much computer- or web-developping- expierience.
It’s every time very cumbersome to find and copy out the marker-link-address from the iframe-code and it’s too much complicated for non-expierenced users.
I want to try to implement this myself in OSM. How can I get the source-code of OSM and how can I send own code to the project? Which programming-languages are used for OSM.
Thanks a lot.

have nice day
