I feel your pain...my solution, I have a few:
A Desktop Gadget: AppLauncher v3.x
Windows Live Gallery
Where you could either drop folders or just single programs to avoid the search through all programs.
It offers dividers so you could group your stuff.
Alternatively you could try this application for the Tray
Download Tray Commander Lite - Freeware Software - Tucows 
again you can group your stuff by several means just try it out.
or look
here for some alternatives to Tray Commander like
Launchy
Pstart
Type and Go
etc.
