You could try Gliffy: it's web based + API... and cheap!

Who could have possibly down-voted this option without a comment... how rude can this be!! – jldupont Nov 12 '09 at 16:49
I think it's pretty useful...last I checked it's free for a small number of diagrams. – davr Nov 12 '09 at 17:12

Had some nice results with paper and a pen,

A camera or scanner if you want to include it in word/oo documents or slideshows.

It's most of the time quite faster, but no reverse engineering possible :)

OpenOffice Draw 3.0

its part of the Open Office package, wasn't designed to compete with high-end graphics packages but is an easy to use, effective drawing tool that makes it simple to create flowcharts

enter image description here

(or)

Dia

It is designed to be much like the commercial Windows program 'Visio'. It can be used to draw many different kinds of diagrams. It currently has special objects to help draw entity relationship diagrams, UML diagrams, flow charts, network diagrams, and simple circuits

I tried this once, but it felt closer to paint than visio. – Joel Coehoorn Nov 12 '09 at 17:19
then Dia is good one ( i guess ) – joe Nov 12 '09 at 17:36

If you are just looking for UML and Win32 you can give StarUML a try.

poseydon has a community edition (http://www.gentleware.com/uml-software-community-edition.html)

It depends on what you want to do. If you just want to do simple diagramming than Dia should suffice. However, if you want to do UML, you can look at a huge range of tools from Wikipedia's list. Likewise, if you're doing database design or wish to automatically extract database schemas you may want to check out something like SchemaSpy.
