Next Prime Number – Have the program find prime numbers until the user chooses to stop the asking for the next one.
Find Cost of Tile to Cover W x H Floor – Calculate the total cost of tile it would take to cover a floor plan of width and height, using a cost entered by the user.
Mortgage Calculator – Calculate the monthly payments of a fixed term mortgage over given Nth terms at a given interest rate. Also figure out how long it will take the user to pay back the loan.
Change Return Program – The user enters a cost and then the amount of money given. The program will figure out the change and the number of quarters, dimes, nickels, pennies needed for the change.
Binary to Decimal and Back Converter – Converter to convert a decimal number to binary or a binary number to its decimal equivalent.
Calculator – A simple calculator to do basic operators. Make it a scientific calculator for added complexity.
Unit Converter (temp, currency, volume, mass and more) – Converts various units between one another. The user enters the type of unit being entered, the type of unit they want to convert to and then the value. The program will then make the conversion.
Alarm Clock – A simple clock where it plays a sound after X number of minutes/seconds or at a particular time.
Distance Between Two Cities – Calculates the distance between two cities and allows the user to specify a unit of distance. This program may require finding coordinates of the cities like latitude and longitude.

Chat Application (remoting style) – Create a chat application which allows you to connect directly to another computer by their IP through the use of remoting and allow your “server” application handle multiple incoming connections.
Bulk Thumbnail Creator – Picture processing can take a bit of time for some transformations. Especially if the image is large. Create an image program which can take hundreds of images and convert them to a specified size in the background thread while you do other things. For added complexity, have one thread handling resizing, have another bulk renaming of thumbnails etc.
Web
WYSIWG (What you see is what you get) Editor – Create an editor online which allows people to move around elements, create tables, write text, set colors etc for web pages without having to know HTML.
