I would like to implement the following functionality for my SugarCRM installation.

Have a page or a section of a page that allows me to input several parameters and submit those parameters to a custom script (say, using POST or GET). The parameters I am going to need will include a predefined dropdown list, a date, and the ID of a certain custom module.

That is, I need the ability to fetch all available records in a specific module and present them in a dropdown list. Alternatively, the whole form could be a part of the module's DetailView and just grab the ID of the active bean, leaving only date and constant dropdown to select.

Hope it's reasonably clear what I'm trying to achieve, if not, please ask, I'll clarify any uncertainties!

What direction should I look into to be get this working? Is a Sugar Dashlet something I could use?
