I'm searching for a User Interface Design tool to visualize a possible GUI in a documentation. I must not generate code. I know that Microsoft Visio provides a functionality. But are there any alternatives?
Which software do you use for visualizing a GUI?
Thank you in advance.
Best regards from Switzerland

PS. Another well-known tool is The Pencil Project.
Thank you for all your replies!!
I'm very fascinated from Balsamiq Mockups! But finally I'm going to use The Pencil Project.
