Using Introjucer for developing standalone programs

Can Introjucer be used for creating standalone programs? I know that it is possible to reuse source code in other IDE, such as Visual studio. I need to use some audio modules from juce library. Whether is it worth to use Introjucer in this case?

Yes, of course it can. When you click on "File -> New Project...." you have several options for standalone projects. For example the "GUI Application".

Or maybe you are talking about intergrating JUCE to an already existing (non-JUCE) project? Well, in that case it probably depends on your project...
