Best RAD tool to develop a complex GUI

Hi,

I am currently using Delphi to build application.
Recently, I have been give a project to display 50 thumbnails on a single
screen.
The Delphi Enterprise edition does not have a VCL component to display a
list of thumbnails.
The only way I can do this is to use 50 TImage components which I do not
think is the right way to do.

Can you recommend a tool that I can use?
For example, suggest an IDE do the job for complex GUI layout.

Thanks.
