Building your own Tools

I am currently working on a project for work where I need to build a web based application that will allow users to enter data that will then be used to generate a PDF form.  I found a great open source library called iTextSharp that is able to do exactly what I want to do.  I was in need of a way to see the editable fields inside of a PDF file and I looked around to see if there was such as tool that I could download and use for this purpose.  After a few minutes of looking around, I thought ‘Why not just build this yourself?’.  So I fired up Visual Studio 2010 and built a really simple Windows Forms application that did what I wanted.  The source code for the utility can be found here.
