Generating vector graphics for laser cutters

I'm looking for a way of generating vector graphics in the following formats for the use of a laser cutter: PDF, SVG perhaps DXF
What I've done so far is write everything in good old postscript and directly cut that.

Now that has some serious problems, one I don't want to deal with it, postscript is a pain in the ass. It's easy to learn, intuitive but I haven't been able to get accustomed to it. Too weird, too little utility stuff like debugging or access to the data structure ultimately used for rendering.

What I also need: Short test cylces, so no sepples, java or other compiled shit. (That goes for cairo as well)
Some ready way to talk to a web server, I want to have my parametic models available at a site, fill out some form and then download a finished layout.

OpenScad would work but it hasn't got real support for 2D graphics, and it's limitations are kind of annoying, you can't even allocate any memory so fuck that.
I'm considering processing, but I'm fishing for alternative solutions.

I should have mentioned cairo and bindings in more detail. The problem I have with that is becomes unnecessary verbose. I can probably migrate most of the boilerplate stuff and then have a fairly concise way of doing stuff. I've actually found a wrapper library "adg canvas", that goes in the right direction and would even spare me a lot of work.
But that's still not the same thing as having essentially the same functionality postscript has in a native library for a common scripting language.

I don't have a choice of the output format, I need a format that corel draw can read as that's the only thing installed on the machine in the shop.
