The first window, the "Large Window" should have a tab bar at the top with tabs for "Messages", "Compose", "Search", "People". The window should have a spot at the bottom for search along with a + icon. The tab bar should have tab states for selected and unselected tabs. You do not need to mockup messages in this window, just the window, tabs and search area.
The second window, the "Small Window" shows an individual Twitter message with icons on the bottom. They should have an active (brighter) state and an inactive (darker) state. I need icons for the following: @ DM RT + - i ★★★★★ ♥ (the i should be a stylized italic i inside a circle like apps use for info functions). Icons should be subtle and not too bright. This small window should have a background style as a gradient (light on top, darker to the bottom) in black. Also provide background variants in dark-red, dark-green, dark-orange, dark-purple, dark-yellow and dark-blue.
- The window styles must be in the dark OSX "HUD" style
- Large Window: 450w x 700h
- Small Window: 370w x 92h
- Fonts MUST be Lucida Grande
See here for a visual mockup of the two windows plus what my messages currently look like: http://qfeeder.com/images/window-mockup.png
http://www.delibarapp.com/ does a great job of this style of window in the HUD style. You can take much design inspiration from that.
