    We are looking for someone to help us get started on a new project. We need an example web application built for us that will have a logon page and then a main screen with a left hand navigation bar, top menu bar and main screen in the middle.We need to hook in all the different screens into the menu and navigation bar (about 20 screens will need to be setup) but we only need to have one screen to be functional and we can then complete the rest. The functional screen will have a simple data entry screen that can be added/updated and on entry will show the contains from the database. As navigation and menu options are selected the middle area will be refreshed with the new screen.We want to use Java, Spring, MVC, Hibernate, Maven, Eclipse. We need a clean implementation so that we can build the rest of the project.

    I am looking for someone who can build me a Swing user interface that I can use to demonstrate the functionality of my simple project management application. My application (partially complete) allows individuals to plan software development projects. You could relate it to something like JIRA or RALLY but I must stress that it is much much simpler. The user interface I require should be able to construct some basic entity objects (I will provide these) from various screens. Some simple checks should be incorporated into the UI when constructing objects (e.g. project name is not empty). In terms of the screens, I have no mock designs so you can either create your own based on my requirements (something similar to JIRA would be ideal although it does not need to be as complex) or I can try to put together some mock designs. The two MOST IMPORTANT things I am looking for is someone who can do this quickly and someone who is reliable. This is an urgent task that I need completed on 20/04/14 so please do not bid if you don’t think you will have enough time or if you have too many other projects to deal with. I need to make sure this is DONE on the date specified. It is a simple task so it should not take long for someone who is familiar with Swing. Further information will be provided to the successful bidder but please do not hesitate to ask me questions if you are unsure of anything.
