URL for multiple markers in Google Maps

In a desktop Qt application, I have some GPS coordinates that I'd like to show on a map. My plan is to construct an URL with the coordinates and let a web browser and Google maps or a similar service do the heavy lifting.

After reading some apparently reverse-engineered documentation at

mapki.com slash wiki slash Google_Map_Parameters

I can make it work for a single point, but what's the URL syntax for multiple points?

My best shot so far is to build a string such as this:

http://maps.google.com/?ie=UTF8&[email protected],17.82&[email protected],17.82

but that will only show "My Second Point". Is there a better description of the syntax somewhere?

Replacing q= with markers= did not work and the "static map" suggestion below only complained about an incorrect API key.

for google maps static there is this URL:

http://maps.google.com/maps/api/staticmap?center=Brooklyn+Bridge,New+York,NY&zoom=14&size=512x512&maptype=roadmap
&markers=color:blue|label:S|40.702147,-74.015794&markers=color:green|label:G|40.711614,-74.012318
&markers=color:red|label:C|40.718217,-73.998284&sensor=false&key=MAPS_API_KEY

Detailed version:

http://maps.google.com/maps/api/staticmap?
center=Brooklyn+Bridge,New+York,NY
&zoom=14
&size=512x512
&maptype=roadmap
&markers=color:blue|label:S|40.702147,-74.015794
&markers=color:green|label:G|40.711614,-74.012318
&markers=color:red|label:C|40.718217,-73.998284
&sensor=false
&key=MAPS_API_KEY

i am not sure if this syntax is also good for standard maps

http://staticmapmaker.com/ - very nice web tool for generating static map urls.

p.s. I know this is an old question, but many still google for it.
